I wish there was more to report but there has been a bunch of head scratching. Working on the cowl I ran into the problem of my naca vent hitting the turbo and not having enough clearance. Crazy thing is 1 of the 2 builds has an issue. My brothers plane is tight but has clearance. Not sure what the different between the two is. Little differences add up when it comes to the cowl. Mine, there was no way that the Naca was going to clear so I had to modify the vent. I am worried about getting enough airflow, but I guess time will tell. I think we are defiantly going to leave the cowls unpainted for possible mods that may need to take place. Mic, one of the dual STI's in Canada sent us one of his 915 intercooler to see if it will fit. I need to get some more ducting and I think I will be able to get the 915 intercooler on the side to work. I am going off Kitfox recommendations to only run on the top of the engine as our last resort. The side should work. Just need to figure out naca vents to feed it fresh air and heat shield it from the turbo/header heat. Once I get the inter-cooler plumbed I think we are back moving forward. I will be able to get the throttle cable routing figured out, which I can then get the panel drilled and get powered coated and ready to start wiring. We can then start pluming the motor and working on the firewall wiring also. While we have been waiting for the intercooler to clear customs I have been working on getting the butt rib close-outs installed. Hinges built and doors installed. Also got the bubble windows and latches installed. I had no mishaps with the acrylic which I was nervous about. I now have taken the doors off and put away for safe keeping until final install. As I wait for parts to arrive for the ducting on the intercooler I think I am going to start working on getting the windshield started, but nervous about messing it up. Fingers crossed! Here is come pictures for now!

Found a K&N filter that fits and now just need to run a little tighter bend to get the discharge side of the cooler to intake. Not optimal running tight bends but running low boost should be fine.

Making more progress with more questions answered this week. In an effort to help mitigate high oil temps we are going to try a heat-exchanger. Should help keep the water temps down on the ground, and help keep the oil temps down in the air. This was recommend to us from Edge performance. Thomas ran one on his engine. Dropped is oil temps 30-40 degrees and only minimal raise in water temps. Spoke with John and they are recommending on the 915 installs to run a lip extension on the bottom of the cowl. I think we are going to cut the cowl and extended the lip 1" to improve cooling. Intercooler is installed and moutning brackets made!
This week I am going to work on getting the heat shielding and baffling done for the intercooler. Waiting on some Naca vents for the intercooler, and also for the intake. Due to the fact that I feel the 915 may be suffering from over-pressurizing the cowl, we are going to go smaller rather than larger naca vents for the intercooler/intake. Also when we add the lip to the bottom we are going to try and increase the amount of exit air, for the added air from the Naca vents. We are going to leave the cowl unpainted, so we can do some testing and hopefully help anyone else coming behind us. Also solved the throttle cable issues I was trying to figure out. I am going to go the route that Doug and Scott went and remove the spring and run a direct cable. Went with the Mcfarlane venier cable but they only sell it in a cable not a solid wire. Thought I would be able to run it into the bing 90 to mount to the throttle body but the cable is too thick to make the 90. With the cable so thick it should work going straight to the throttle body. Once I get it all mounted I will post some pictures that will make more sense. Worked on building a throttle arm and mount for the cable. Finished cutting the panel for the throttle cable and now hopefully my brother can get his done this week so we can get them off to the powder coater. Now its time to start plumbing the engine and as soon as I get my panel back start on wiring. At this point I am doing as much as I can but I seemed to be waiting on parts. Should hopefully in the next couple weeks also receive our new intake that mounts the injectors on the inside.....fingers crossed!

Slowly but surely....... Progress update.

I have been working on ducting for the inter-cooler and heat-sheilding the inter-cooler. Inter-cooler can be an interheater if not done correctly. Trying our best to make sure we keep the heat from the engine from heat soaking the intercooler. Only thing left to do on the heat shield is install some heat shield.:D I think I am going to use the HP insulated heat shield to line the aluminum. We will also use it to protect the fiberglass bottom naca to keep the turbo from cooking the cowling. I have used this stuff next to the turbo on my snowmobile and it has held up when the turbo starts glowing. Naca vents are also going in for the intercooler and intake to the turbo along with radiators. Installing therm with some fiberglass resin. This week hoping to get the panel back from powder-coater and get it off to get silk screened. At this point just hoping to continue to make progress and keep figuring things out. OH.... Big news! Third time is the charm. FAA kept send back the registration but just recently received the registration back from the FAA! They are both officially registered.

More cowling work this last week. Installed a lip right before the radiators to ramp airflow up into the radiators versus around the bottom. I took compressed air and tried to simulate airflow and found most air was flowing underneath the radiators. Also worked on baffling around the radiators to keep airflow going into radiators. Also worked on getting exhaust cut and cowling trimmed. Need to weld in bunge for the A/F ratio sensor. Stinger needs to be loose to install the cowl and pivot in-order to get ducting up and over the radiators. Access to the t-clamp should not be a problem, as I will need to loosen the t-clamp so stinger can pivot when removing bottom cowl. I think if I opened up the exhaust hole more I may be able to remove bottom cowl without loosening the stinger, but for now I think I am going to keep it as is. Still thinking on temps and keeping things cool, so after seeing others results by adding the bottom lip, I decided to drop my lip down. Added 1.5" to the bottom lip and I left it long. This should increase lower pressure and it also improved volume of "exit" air. Also reinforced the bottom lip to keep it from moving under higher speeds. Powered coating of the panel turned out good. I used lab metal to fill in rivet holes and after powder coating so you cannot see them. Never got a picture before I dropped the panel off to screen printing company that a local avionics shop uses. They are 1.5 weeks out so I think I am back to cowling work. I have lost track but I think I am literally over 50 times of removing and installing cowling:( This week hope to finish camlocks now that I am done needing to check and recheck cowling.

Cowlings....cowlings.....cowlings. More work on the cowlings this week. I got called out to work and I thought I would be traveling for most of the week. The schedule changed so it was day trips for most of the week. The wife decided to take the kids to Logan to visit her sister so I was able to log some more time! I got the panel back from the screen printer and it turned out good. I am realizing building a plane is like building a house. There are lots of imperfections that you just have to accept and move on. Trying not to look back but look forward. My fingers are raw from installing the cam-locks. Wow those take a lot of time. I can't believe how much work the cowlings have been along with the camlocs, glad I got them all knocked out this week. My work schedule this coming week looks like I have a few good days for building this week that I am hoping to finish plumbing the engine and then I think I have finally reached the daunting job of wiring. I installed the panel and throttle cable installed. I am please to report that the throttle cable works great. Thanks Doug and Scott for help on this! The only thing is I had to use two graduated sleeves from the rotax 912 throttle cable attachment. In so doing the bolt is not long enough into the nylon nut. I have ordered an all metal lock nut and a low profile lock nut to try. Other than some more finish sanding and painting the cowls, which I am not going to do until we fly, they are finished!

Gosh darn that is sooooo cool! You are going to need a step ladder to get into her, and then a mirror on the skylight to see what to do next!!!! I only have 26" tires for mine and expect that she would rather have the 29" as shown, when said and done! Thanks for sharing the passion of the hobby.:cool:

Engine is plumbed minus the intakes because I am waiting on the new inward facing injectors from edge. I have been promised them "soon". The oil to water heat ex-changer fits nicely and I am hopeful it helps in keeping oil temps down.
My reading to work ratio has seemed to get out of control. Feels like a 10:1 right now and my head hurts from mentally trying to wrap my mind around wiring. With that being said I feel like I have made some good progress, at least feeling like I have a clear path now. Almost finished wiring up engine side, with all sensors and indicators going to GEA-24. Going to next start working on vertical power and figuring that out. A couple things I learned. If you are using a UMA temp sensor it needs to have a R for it to work with Garmin. Also trying to figure out how to hook up oil pressure I learned that the new rotax oil pressure sensors operate via voltage variation and now require a resistor in line. I called Stein Air looking for a resistor, and because wiring them are a pain, they decide to build a small pcb with the resistors for the oil pressure and for the RPM built into the board. They where 20$ for 2 shipped. Also installed grips and PTT switch on the control sticks. Thanks Nikk for these. I think a few where wondering on the PTT switch and where to get them. You can get them off amazon. Here is the links for everything. Regular bike grips are too long, so you need to get shorter ones FYI.

So I have decided to start building early in the morning before the kiddos get up and have me going other directions. Pretty quiet and lots cooler. :) I have been dreading the wiring, but now that I feel like I understand it somewhat, its not nearly as bad as I thought. Of course I will probably be singing another tune when I am trying to trouble shoot issues. Not sure if the pile of wire is an indication of how much I have accomplished, or how much wire I waste. I received new intakes with the inward facing injectors, so I switched those out. Need to run the final length of fuel line. Firewall forward is completely wired. Fuel pumps are wired. Ecu wired. Heater is done. Bose 6 pin headset plugs are wired. USB ports are done. Radio and PTT is wired.

I need to finish transponder, and GPS-20, Trim, autopilot servos, ELT, can bus. Its crazy how much wire are in these little planes. A lot more than I would have ever guessed.

Your wiring looks great so far. Very clean. I like your ground bar. The one I bought was more compact, and it doesn't look as clean.

I built the majority of my plane between 4:00AM and 6:00AM in the morning. Everyone else is still asleep, so I didn't feel like I was stealing time from my family.

My wife however, is quick to point out that I was asleep by 8 every night, so I guess you pay the piper some time.

Ha! That’s the same thing I am doing! I seem to be going earlier everyday. This morning I started at 3:30am! I keep telling my wife I wish there was a pill. She laughs and says there is but you will would lose your medical.:)

I am usually too lazy to walk over and take some pictures. Cory is about a month or so behind me. He got sick, then got burned out so he took a month off. He is back at it now. Because there is a lot of unknowns with the engine install, the plan is to finish one and then see what mods need to be made to the other. His cowl is cut, just waiting on Naca ducts....ect. He is getting close to start wiring. I am trying to get wiring done first, because only one can wire at a time. Only bought one set of tools.:)

Does anyone know if it's not high contrast if that could be an issue, like same color of the aircraft?

aviator79

08-13-2019, 11:49 AM

It could be. I'm certain in can't be the same color as the aircraft unless you have a very generous and lenient DAR. From the AC:

7.3 N-Number Legibility.
The N-number is required to be legible and written in capital Roman style letters without any ornamentation. You may use shading or a border only if it makes the number more legible. Use the following guidelines:

7.3.1 Make sure the color contrasts sufficiently with the color of the fuselage to make iteasy to read. Be especially careful when the background is highly decorated, as in checkering. Consider applying the requirements of 14 CFR 23.811(c)(7)(ii) or 14 CFR 25.811(f)(2), Emergency exit marking, as a test of whether the color of the N-number contrasts sufficiently with the background.

Do you know who will be doing your inspection? You could ask him his opinion before you do anything permanent.

Do you have any type of short circuit protection between the positive lead on the vertical power and the mater contractor? I see the VP lead goes through your firewall (as does mine), if that grommet chafes I believe it would cause a major short. Also to note, I think the earthx batteries have internal short protection but Im not sure if this is what is relied on to protect the main power runs. The manual states it will reset after a cool down period if about three min. I think that would mean if you had a short it would disconnect, then momentarily reconnect every few min?!?

To that point if the battery internally disconnects the only backup option for avionics power would be a secondary backup battery, as a backup critical systems bus would not function.

Any clarity on this would be appreciated and Id love to know what people are doing to protect from shorts on the few connections that go straight to the master contractor.

Thanks!

I don't have EFI (yet), so I'm not quite as dependent on my fuel pumps. Nonetheless, the 914 does have two fuel pumps and I do run one fuel pump through my ACM (sort of equivalent to the VPX), and one on its own dedicated circuit. If (when) I do EFI, I'll keep this arrangement for the reasons you state.

Also, I used something like this to pass power through the firewall:

Shadowrider

08-14-2019, 09:15 AM

I contemplated running one fuel pump outside the VPX. Couple reason I didn't. One is the VPX monitors the circuit and if amp draw is outside the set parameters it will alert you. I wanted each fuel pump monitored, but now I am relying on the VPX. The other reason is I was having a hard time wrapping my head around how to run a fuel pump outside the vpx and to do it safely.

JoeRuscito

08-15-2019, 04:49 AM

Joe, no short protection on the positive lead from the battery to VPX. Personally I don't think its needed. I think it would be more likely that the fault protection breaker fail versus chafe through the grommet and insulation on the wire. My alternators tie into the vertical power/battery that run through a switch/breaker so they protect the electrical from the charging system. The fault protection on the earthx battery is to protect the lithium battery and to keep a thermal runway from happening which typical happens when overcharging occurs. The fault protection also protects the battery to try and save the cells if the volts get to low. Basically if the volts drop to low it shuts off the battery to save the cells until hopefully soon a charge gets put on it.

I am not running a backup battery system. The electrical system I would run would be completely different if this where an IFR plane. VFR Day aircraft I am not too concerned if I lose avionics. I will just look out the window which hopefully I already am. The one concern I do have is there is a lot riding on the VPX. If the VPX dies, suddenly I will find myself on short final, with both fuel pumps running through it. I may take a closer look at the VPX pro that has a dual bus system so you can run one fuel pump on each bus or possibly run one fuel pump outside the VPX on its own bus. Of course the biggest concern I have with this aircraft is its engine is a piston engine and there is only one.:)

Hey Dustin, As a follow up talked with Earthx and they confirmed that no fuse is needed to protect the battery. Although another kitfoxer pointed out that the rotax generator still needs to be protected against shorts. Which I believe it is by the 2 30 amp fuses. One on the AMP connector pin 3 and one coming from the start power switch (912is).

On the subject of back up batteries. Do you have any concern the voltage will drop below the EFIS and engine monitor min voltage on start up? It seems this is a good secondary reason for backup battery. However with lithium (14 volts) and min efis voltage around 9 it seems like you'd have to have a pretty dead battery to have the EFIS drop out on start.

Shadowrider

08-15-2019, 07:09 AM

I have thought of this because it seems a little disconcerting starting the engine with avionics powered up for fear of power cycling things on the start. But with all engine gauges being digital kind of need avionics on for start.

Shadowrider

08-16-2019, 03:13 PM

This is what I decided to do. Master turns on GDU 465 and GEA-24. So I will have engine instruments displayed on the G3X. Have not tried to start yet and see if it power cycles the GDU.

Its alive! At least the avionics are. Wiring is done and troubleshooting is done, or until I run engine and find any possible problems. I must have an ADSB antenna in range because I am picking up traffic and weather. Radio checks out and I am able to pickup the local airport and had a plane give me a radio check. Getting ready to start the engine but still waiting on a prop. Troubleshooting went faster than I thought, which is a good thing. I guessed which was signal wire on the egt's so had to switch pins as they where indicating backwards. (I was testing them using a heat gun and they where going down in temp) I had trouble getting the trim to work. Its really frustrating to trouble shoot something to find out its not you its the box. Apparently both safety trim switch boxes went out without a jumper pins internally so I was not getting 12v signal to trim motor. So far I have been impressed with the Garmin G3X. Ipad is also talking with the GTX45R so its receiving traffic and weather via ADSB. Its also talking with G3X so attidue and WASS GPS is being received from the G3X. The Ipad is also talking with the AFR so tuning the engine will be possible. Starting to get excited! (Those with a keen eye, I had selected the wrong manifold pressure gauge, its fixed now and I selected the wrong input for the earthx fault monitor, its fixed also)

Starting to see light at the end of the tunnel. Maybe a little slight flicker.:) Okay I finished all the wiring. I decide to run an audio jack from the ipad and tie it into the intercom so you can have sound from the ipad. I also put a red LED under the dash that shines down on the center console to help you see at night. I also ordered the baja designs S2 sport. They showed up and they did no seem very bright. Looked online and found out they have a pro that is almost double the lumen. Installed the baja designs s2 pro and they are much brighter. Its not that the sports was not bright, but compared to the rigid taxi lights they where not near as bright and they had two leds not one. Now the S2 pros are very bright. Going to pull it out tonight when its dark and check how it looks. With that being said, that was the last wiring I needed to do. I remove that grip locks ties and temporary Velcro securing straps and got the lacing string out. Did a final secure of all the wires as I have now checked everything. Fuel pressure and fuel flow are both indicating correctly I also finished flushing out all the fuel lines, flushing out the header tank, leak checked everything and secured all the fuel lines. I did a fuel flow check also. It flows 46.5 gallons per hour. I think that will be sufficient. I think I am ready to start it. Prop showed up just in time so I also got that installed. I set the pitch to 19 degrees from recommendations from Jason. List is getting shorter of things I need to do. I pulled it out and calibrated the ADHARS and also the magnetometer. I will do these again when are the airport, just wanting to make sure no surprises. Things are starting to cool down a little so my brother is starting to work on #2. (His garage gets hot) He has anodized a few parts to go with the edge orange.

She is alive! Engine start went well. I discovered a few more problems. One of them is kind of major. Couple things happened. First we had outdated instructions that showed the fuel filter before the pump. With that we also put fuel flow before the pump. Reading through the manual for the RED CUB fuel transducer, I missed that the fuel flow sensor MUST be after the pump. So you can guess what I did? Filter and fuel flow where before the pump. So this was kind of major to change but needed to be done. Stuff like this bugs me so I worked through the night and had it back running the next day. Had to take intercooler off and redo the fuel system. Had to move the pump and filter and flow meter. It was major, but got its done. Fuel flow now is reading accurate. The other problem was the AFR. Had to get help from the company to reflash the setup. Its not working correctly. I will post a link to the video of the first startup. Notice the smoke on startup from oil in the exhaust from changing out the turbo.
Ran it in the evening so when it got dark I could test the lights. I ran it the next day with the flow meter moved, fuel flow and AFR are now reading correct. One of the pictures is showing engine gauges after 15min ground run at 2000rpm. Things are looking good. She is squawk free!

Nice going Dustin. That was fun right? Glad everything is worked out. Im kinda the same, discover a problem and then can't rest until its rectified.

Shadowrider

08-29-2019, 04:10 PM

Yeah! This is defiantly the funnest part of the build. Eddie I used the gates fuel line you used and it still smells like fuel in my cockpit. I have quadruple checked everything and I have no leaks. If I stick the fuel hose to my nose it smells like fuel. Is this how it should be? I am guessing the other fuel line must be pretty bad then and maybe up close this still smells?

aviator79

08-30-2019, 05:26 AM

Hey Dustin, Gates manufactures a lot of different fuel line products, so just to be sure, did you use some version of Gates Barricade (low permeability) fuel hose? I used this in my plane and I do not have any fuel smell in my cockpit. I haven't stuck my nose right against the line, but maybe I'll try that.

Shadowrider

08-30-2019, 05:59 AM

Thanks Brian!
Its definitely not as bad but still has a fuel smell. I am just very sensitive to fuel smells right now worried that I have a leak. If I stick my nose on the gates lines it smells of fuel mixed with rubber. I used Gates 4219XL. I am thinking I may change them out. What line did you use?

efwd

08-30-2019, 12:12 PM

I had this same scenario Dustin. I spoke with John M and I was informed that auto gas is far worse than 100LL. If you have the same lines I have, it will get better. Not sure if you are using 100LL for the initial run ups. I was using auto gas.

So the list is getting shorter! I need to install windshield, (its ready to go on), boot cowl is getting painted, turtle deck, install interior, install flapperons, rig it. Then I am going to move it to the airport. What do I need to move it? Isn't there a rod that needs to go through the tail? I see some have supported the tail with tires? What is recommended? Any and all info welcome. I have a tilt deck flat bed that I will be using. Thanks in advance! Wings will be on and plane should be complete when I transport it. I have about 15mile drive ahead. Good thing I am adjusted to getting up at 4am as I think that is when I will move it. Probably will be going about 1 mile and hour so I should make it by 7pm. :)

efwd

08-31-2019, 08:27 AM

There is always the transport kit offered by Kitfox. But, some people have just bent up a few pieces of 1/2 " pipe. You will need a length that supports the front spar down to the lift strut attachment point at the bottom of the airframe. You will also need two more that will attach to the through pipe at the vertical fin transition. These will attach at the other end to the wings at the strut attachment points. You will need to protect the vertical tail from the flapperons. The transport kit comes with the sleeve to slip over the top of the fin and the foam pads that are attached sit between the flapperons and the vertical stab. I supported the underside of the airframe with three tires as Josh did. I traveled at 55mph on the freeway. No need to crawl. Just make a safety stop and check it all out for security a few miles down the road. Nonetheless, you'll be glued to the rear view mirror. I like my transport kit. I feel that it gives me a bit more piece of mind should I need to retrieve my plane from someplace with a trailer. I would be stuck otherwise since you will certainly ruin it trying to transport without the support. I posted pics of my transport kit someplace long ago when someone was looking to fabricate their own. You can try a search on the subject I suppose. There are a couple threads titled Transport Kit. Several pics are there on the second page of threads.

Added notes on transport...

Tie down the front at the gear, meaning the wheels/tires. Let the main gear provide shock absorption to the fuselage. Do not strap the front of the fuselage down.

At the rear, use the two 5/16 carry through tubes to anchor the rear with proper support... not on the tailwheel spring.

Congrats on the engine start! Just catching up on your build... I take it there was no issues with the G3X going down while cranking?

Shadowrider

No issues none at all. VPX does a good job keeping g3x alive. I put g3x and gea-24 to the master switch so I have engine instruments while cranking. Then the rest of the avionics on the avionics master. Its sweet how you can just change things around as needed.

Had a productive week and put in the hours this week. Ever since starting the engine it has helped push me to get this thing done. Thanks Brian for your info on cutting the turtle deck. It worked perfect just how you described. I was able to cut it with a thin slot and still remove it for swinging the wings. I ordered some tinted polycarbonate for the side windows to match the other windows. I polished the center caps for the hub caps and have a friend who is going to lazer engrave them for me. More to come. I extended the aluminum angle pieces so I did not have to notch the glare shield and it slides down below the boot cowl.

Turtle deck is a ton of work. Glad that is done. I was deciding if I should use the hinge, but decided with the hinge you can remove the turtle deck without putting a big cut. I also switched out the hardware for a lower profile button top hardware.

I need to weight it, set the prop, do some power checks, and then get it inspected. All these task will happen at the airport. We are moving it to the airport tonight!! I opted not to use a travel kit. I am going to leave the wings extended and put it on a tilt deck. Going to be a adventure tonight! Technically tomorrow morning. If the weather clears we are going to try at 3am. Good thing I am used to waking up then, but my brothers not so much! We have a friend who is a sherriff who is going to give us a police escort to the airport. Hopefully the next time I report back its sitting in the hangar. Fingers crossed.

3am taxi test.....PASSED.
N33TF is parked in the hangar with no damage. Everything went according to plan. It was 12 miles and it took us about 45 min. 32' wingspan seemed really big when you are pulling it down some small city streets. Didn't realize how many street signs and trees are on the side of the road. We had quite the motorcade going down the road. Glad that is done. I will post more pictures later. Quite the adventure. Next time I think we fold the wings and use the travel kit.

09-15-2019, 08:32 PM

Moved my final inspection up! Monday Sept 23. I "think" I will be ready. Trying this week to finish up paperwork. I have been working on tuning the engine. I have about 1 hour of run time and I am starting to understand the ECU. I started out doing some pulls and thought I had a boost leak. Turns out it was because I was way over-pitched on the prop. I have been adjusting the wastegate on the turbo and I am now starting to build good boost. Saturday I did multiple pulls on it and I am currently at 42 inches of MAP and 5600 rpm. I am going to add another 1 degree of pitch, which will put me at 14 degrees. From there I will see where I am at on rpms and then adjust boost if needed. I have the tail strapped to keep her from leaping down the taxiway. It is a little sketchy running at WOT as I feel the motor is screaming right now. It defiantly gets hot but I am feeling better about cooling. Ran some heat shield, which took the bottom naca from not being able to put my hand on it to cool to the touch. I ran it for about 15 mins doing 5 hard pulls. Water temps peaked at 210f and oil peaked at 163f. OAT was 86f and winds where calm. Intake temps at 42" was running around 110F. Intercooler is getting heat soaked after sitting when the engine is shut off. Intake temps peaked to almost 200F when the engine was shut off and just sitting there. Once I start it and start coming into boost the temps drop all the way down to almost 110F. So intercooler is doing its job and and when in flight I should see quite a bit more drop in temps. Cooler temps=more HP=:D I am thinking with airflow I will be able to keep temps in limit based on what I am seeing on the ground. At first I was a little skeptical that the 155hp is accurate rating. From one dyno to the next, the numbers can be different based on so many variables. When I was first doing runs and only getting 37 inches of manifold fuel flow peaked at 7.9GPH. Based that the efficiency of this engine compared to the 915 I think fuel flow will give you ball park power rating. I read reports that the 915 peaks at around 10-12 gph. I was only flowing 7.9 which is no where near 10-12. (141hp) I was not sure this edge engine is going to be making 155hp. Looking at the data log, last pull was 42 inches of manifold and fuel flow peaked at 11gph. 47" MAP at WOT and its going to be screaming pretty good, and flowing lots of fuel.....mind changed.

Now that I have run it and done multiple heat cycles my idle is around 1800rpm. Tomorrow I am hoping to bring that back down to 1500-1600 and re-calibrate my TPS. Hopefully I get pitch and boost dialed in. Then its time to drain the tanks and get it weight. My goal has always been sub 900. I may have already weighted it but it had fuel in it.:eek: I need to weight it and check the arms for weight and balance. Stay tuned!

Here is a shot on how to cut slot for turtle deck. I needed to be able to remove the turtle deck to fold wings. Key is to cut an angle cut toward front of turtle deck so the front turtle deck will come off to swing wings.

Unfortunately when I woke up this morning I have some type of cold that is bugging my ears. I am hoping full recovery shortly, but I am going to wait until I am feeling better for the first flight. Inspection went good. I forgot to placard my baggage max weight. Had the label maker handy. Thanks Eddie for that idea. Printed a label and we where good to go. Other than that things went smooth. It took about 2.5 hours. 1.5 worth of the paperwork/stories and 1.0 of inspecting plane. He went over pretty much everything. I did not need to remove the wingtips, or side panels of center console. I did have the seat out and the cargo bag folded down for him. He found two bolts on the pully's for the rudder cables that where not showing a full thread and half like is called out but said he is not concerned about them coming loose but maybe change them next year on the annual to slightly longer bolt. Glad to be signed off! Looking forward to first flight!

Congratulations Dustin!
I have settings for the AP but my links on the push pull tubes are connected to the servos on the wrong location of the arm. The links are supposed to be on the first hole of the arm nearest center. I think you can safely get to the accurate settings safely enough if you just follow the setup in the manual. Make sure your at a safe altitude before you switch that thing on. Those servos are powerful and can make changes pretty quickly.

Tomorrow maiden flight is a go! Did another full static engine run, leak checked. All looks good. I hooked up a scale and I am getting 650lbs static thrust at a DA of 7000' It has more boost in it and Edge is saying if I turned the boost up more I will likely be over 700lbs. I think 650lbs will be good for now.:D I did my high speed taxi test. Its funny, our local tower always is friendly and very accommodating when I am in the challenger. But now they where not to friendly to me requesting a taxi test down the runway. I think I may need to take them a box of donuts tomorrow morning and discuss with them my plans.

I got the tail up and she got light on her feet. Flight controls felt good and directional control felt good. The mains may have lifted off when setting the tail down.;) I glanced at the IAS and I saw 34. There will be two Kitfox's doing the Maiden tomorrow and they are both named Dustin;) I was very tempted to just take it up, but I wanted to do one final check over everything. I am starting to catch the vision of this flying, taxing with the door open and the wind in your face. :D

Shadowrider

09-26-2019, 02:48 PM

Thanks guys! It was fun, and scary! Honestly I was not but intending to climb that steep. It just leaped off when I rolled the power in and that was me holding it back🙂 I just wanted lots of altitude quickly. Vibration in the stick was bad enough it had me concerned. Below 5000 rpms it was acceptable. Took it up to 9500msl did some slight turns, three stalls and came back and landed. Power off flaps up she stalled at 47 indicated at 9500msl. I am not running VGs or the stall fence so that number should improve. Right now she is grounded. Edge is more than likely putting out a SB on the mufflers. They went to a 2” exhaust which flows more and makes more power but is stressing the end cap on the mufflers. I am going to gusset mine until the new one shows up. Headed to the dunes this weekend, so hopefully back going next week. I threw a GoPro up for the maiden that I will have to put up.

efwd

09-26-2019, 03:03 PM

I wondered if that's what happened. I too came off the ground and it went for the sky. I had to push the nose down to avoid the severe angle. It can do the angle (the plane) but I wasn't comfortable at that moment. I think I let it climb for the same reason. Altitude is your friend. However, now I have seen the video Steve put up and I will be doing some practicing on that light in the seat method.

What a fun day! Kids where as excited as I was. They came down early before school! Grateful to my wife and kids for being so supportive in this journey! I edited it down because I have a short attention span! Just realized I put the wrong date at the start of the video. Oh well you get the idea. Enjoy

Thanks guys!

Okay here is the down and dirty. CHTs and oil temps are looking good. In fact I think I may have too much cooling..............maybe? I guess that is better than not enough. On the first flight oil temps only reached 130F and CHTs only reached 175f. So far she is running cool. Of course OAT was 60f. Intake temps where 120f with a max manifold pressure of 49" momentarily. I then pulled the power back to 40" for the climb out. I am going to adjust boost in the ECU. Egts had a split of 75F split between #1 cylinder and #4 cylinder. Not a real big deal but nice thing with this ECU is you can add or subtract fuel trim to get them closer. I am going to add some fuel to cylinder #4, which from what I understand is normal to run hotter in the rotax. Bad news is I found a crack in my muffler where the down pipe bracket is mounted. I have been concerned from day one that the stainless is going to fatigue and crack because its a little thin walled. I contacted Edge and they are in the process of a re-design to address the issue. They will be sending out new mufflers because when they went from 1.5' downpipe to the 2" downpipe fatigue cracks have been showing up. In the meantime I have got it welded up and added some gussets to keep it from cracking again. Hopefully tomorrow I can get the repaired muffler back on and finish balancing my prop. If everything goes well I am hoping to take it back up. When I stalled it first flight I did it with no flaps and power to idle. It buffeted at 47IAS.(MPH) I am going to start adding flaps and checking flight controls with flaps. I still have lots to do on the build. Stall fences still need to be built. Wing cuffs need to be built, its windy without them. Install VGs at some point also. Then we need to get #2 finished up now that I am pretty sure our cooling is going to be sufficient.

Gussets are only welded on one side to help keep from heat warping pipe and that is anti seize on the inside to help slide in the down pipe.

It's impressive that you're running so cool with that firebreather up front. Do you have an oil thermostat? IIRC, you installed a coolant/oil heat exchanger. The oil thermostat might bring up both your oil and CHT. I bought one from a race supply with a higher setpoint than the one sold most often for Rotax (205 F), and have had great luck with it. Oil temps are almost always in the 190-210 F range. I guess you could also consider taking out the heat exchanger. Right now the indication is that it's doing its job too well.

Shadowrider

09-30-2019, 07:04 AM

Brian I am not running a thermostat as I figured I would be running into heating issues. I think the biggest thing is by dropping the lip and giving more exit air, its really doing its job. The heat exchanger was to help bring down the oil temps as I figured they would be running hot. It should also bring up the oil temps when the water temp is higher than the oil. With CHT at 180 and oil at 130 the heat ex-changer is heating the oil and cooling the chts. I will have to try and fly it when OATS are a little warmer and get some better numbers. I was building as fast as I could to try and get it up flying in the heat.......oh well. I may need to look into running a thermostat. Why did you run the thermostat that you did? Do you happen to have a part number for it?

aviator79

09-30-2019, 07:37 AM

I ran the thermostat with a higher setpoint for two reasons:
1) Normal operating range of the oil is 190-230 F. I'm not sure why the setpoint on the commonly sold thermostat is 180 deg F, but it seems too low, especially given that some oil will always flow through the oil cooler, so when it's chilly, the thermostat won't be able to regulate right at its setpoint.
2) Looking around at my Kitfox bretheren, most had more issues getting the oil warm than trying to keep it cool, with many 912 operators installing shutters in addition to the thermostat. A higher setpoint lets you actually get to temp before your thermostat starts opening, so you have a better chance of hitting 190.

Caveat: If its's really cool, or you have really good flow across your cooler, then there is some point at which your thermostat can't regulate at its setpoint. The thermostat always lets some oil flow through the cooler, so even when it's "fully closed" you may not be able to keep the oil at the setpoint. I've been pretty lucky that even when it's pretty dang cold out, I have no trouble getting into the normal operating range on every flight. When it's cold, it may stabilize below 190 in cruise, but I guarantee I'll hit 205 on takeoff/climb. This isn't due to great design on my part. I picked a thermostat based on intuition without analysis, and got lucky. \

As a data point: coming back from Phoenix yesterday, at 11,500' 42F ambient temp, 30" MAP/6.5 GPH, oil temp was 190. Obviously your entire setup is very different, so I don't know how useful that is.

It might be good to make this topic a separate thread, but I'd like to add a few thoughts to it now. I have the common oil thermostat sold by Lockwood, Aircraft Spruce, etc. for my 912 ULS. It does have the 180 deg. setpoint, and I think that is probably good, although I think that the thermostatic element in it is also possibly available in other temperature settings, and can be replaced. Even in really cold weather the 180 deg. target of the valve is reached on my engine, but then it drops below that before it closes down again. So on cold days it averages less than 180 deg. It also brings my oil temperature up faster after engine start compared to another friend's without a thermostat, so that is good. Now, to throw out a couple of other points - the common and recommended setpoint of a Vernatherm oil temp control valve on a Lycoming is 180 deg. Lycoming is concerned with moisture in the oil just like Rotax is, and 180 deg. has been shown to do the job. Why? I believe because inside of the engine the oil quickly reaches much greater than 180 deg. on the surfaces of the cylinders, etc. On my Rotax, the oil temperature is measured at the oil pump, after it has left the cooler and before it enters the engine. When it gets inside the engine it quickly gains temperature also, I believe well above the necessary temperature, and water vapor is expelled out the breather system. I also believe that lower oil temperatures (within reasonable limits) are better from a lubrication standpoint, regardless of multi-viscosity oils. I'm sure there is going to be disagreement about all this, but one final anecdote... my friend Stan's original 912 on his Mod. IV, which was a 1200 hr. TBO engine, was outfitted with one of these 180 deg. valves, and that engine (which was still running well) had, I believe, 2500 hrs. on it without any major repairs necessary when he replaced it with a new one last year.

Oh, I also wanted to say that the thermostatic valve you found looks like a very good one!

Thanks guys! Trying to figure next steps. I think I finally got prop balanced. Ended up and .09ips. It’s .6ips around 3500 rpms but 4500 and above it smooths our. Flew today and at 9500’ MSL OAT was 33f. Oil temp peaked at 132f and CHTs where 175f. As I leveled off oil dropped to 110f and CHT dropped 155f. I am going to verify oil temp gauges are indicating correctly with a temp gun but I think I have plenty of cooling? I think I am going to start taping off oil cooler and see what that does for me. My new theory is I dropped the naca to clear the turbo and in so do doing I changed the pressure which increased velocity of the air, improving cooling. 🤷

aviator79

10-01-2019, 05:58 AM

Good idea to verify that oil temp. 110 does seem cooler than I'd expect from dropping the NACA and adding a tripper lip.

John's points are all perfectly valid. The 180 degree thermostat is probably perfectly adequate for the job.

Shadowrider

10-02-2019, 06:42 AM

Temp is verified and correct. I taped over the oil cooler with aluminum foil tape. Covered 50 percent and temp only reached 150f oil and 180 water. OAT was 65f. Powered back for landing and temps drop to 110f on the oil and 140f on CHTs. I am going to keep taping up until I get around 180 max temp on oil. I guess it’s easier to restrict cooling than it is to try and add. Did the 3 flight yesterday and still can’t seem to get the prop balanced to acceptable level. Wondering if I have vibration coming from engine possibly? Vibration seems to be higher frequency than the prop rpm. If I let go of stick I see the stick vibrating almost buzzing. I tried to video but it’s not showing up. Going to try changing frame rate. Last time I flew in a kitfox was long enough ago I can’t remember vibration levels.

Dustin, Just want to make sure you have also checked your prop's tracking. While I run a fixed pitched sensenich I have found that after torqueing its important to check the tracking as well. Just a thought. Bruce N199CL

Shadowrider

10-02-2019, 07:27 PM

Thanks. I did check blade tracking and one blade was off 1/4" out of track. I was able to get it withing 1/16 by adjusting prop in hub before tightening it. Still didn't help balance. Fortunately Steve from Dynavibe spent a lot of time on the phone with me to help to configure and sort through some problems. I did learn that my spinner is really out of balance and sometimes causes issues when trying to balance. I was able to estimate the heavy side of the spinner, rolling it on a table, and put the heavy side on the light sight of prop. I then decided under Steve's direction to take all the weights off and start over for the umpteen time. First run was .80ips. Second run was .30ips. Third run was .05IPS. Steve said to call it at that. He said its hard to get better than that in these light aircraft. I about had a party I was so excited! Time to pull cowl and do I once look over, then its time to head out to the practice area and get the AOA calibrated. Hopefully start putting some time on her now! Oh, I did cover the oil cooler so now there is only about 1" showing. Full power climb and the temp barely got to 160F. Oat was 60F. I think I will probably leave it there for now??

aviator79

10-03-2019, 06:12 AM

Maybe consider losing the heat exchanger for a thermostat? I guess you could keep both, but weight and complexity wise, I'd try to keep it simple.

PapuaPilot

10-03-2019, 09:05 AM

That's good news on getting your prop balanced; .05 IPS is very good for a piston engine (I can get the PT6 props a lot better).

Did you mark relation of your spinner to spinner bulkhead? If not make sure you do, you need to maintain that position for the prop to stay in balance.

Update!

I have about 10 hours on the aircraft so far. I have got the tune pretty close to good. I am never much of a fan of running a engine on the limits and would rather just burn a little more fuel for that piece of mind. Its crazy how hot these engines are rated to run. (Rotax EGTS temp limits) I am really liking the data log from garmin. I have not taken the laptop up with me to tune, so instead I just pull the data log and use that to tune the laptop for the ECU. By comparing what I am seeing on the data log I can get the data field on the ECU that controls that parameter. I have been learning the ECU and getting more comfortable with tuning. I don't claim to understand most of the ecu, but it is nice to be able to zero in the exact spot for tuning. I have trimmed the egts to get them within 15F of each other now. Takeoff I am now seeing 11.5AFR and 12.5AFR for cruise. This is on the very conservative side I know. My opinion is I am not losing that much power running it rich, and its easier and safer to makeup the power by just turning the boost up.

GOT THE TIRES DIRTY!
Went out to start getting some landing practice. I flew to U14, Nephi, and did some landings on the dirt next to the runway. I am not pushing it yet, but takeoff and landings are getting real short! I have been working on full flap landings and approaching slower. Right now I am getting comfortable approaching at 50MPH. I still have my shocks at 150psi, which feels to stiff, and the tires are still stiff at 12psi. I have left the tire inflated hard for the long taxis I have had at home airport. Trying to see if I can talk the airport into letting me takeoff in the grass and not have to taxi the entire 8500' runway we have. I then flew up to Desert Airpark and tried landing on the dirt strip out there. I am getting more comfortable landing, doing wheel landings and 3 pointers now on q!

I have been pushing the altitude higher and higher each flight to make sure everything is working as expected. I am now up to 14500' and need oxygen to go any higher. I have gotten soft over the years flying a pressurized cabin and I was feeling the effects of hypoxia. I have previously tested the effects on me and first thing I notice is a head-ache and vision sharpness starting to go. I stayed at 14500' for a short time and dropped back down to 10500' and immediately started feeling better.

Everything has been going fairly smoothly with just little adjustments here and there. I did have an issue last flight with my transponder that I can't figure out. Worked great for 2 hours of flying. Landing and did a couple touch and goes and after one touch and go I got a transponder fail box. I tried powering it down and back on and nothing. Landed and shut everything down. (This is usually the solution on the challenger) Turned on the garmin into config mode. Everything was showing normal. Restarted and transponder was working normal. Did some touch and goes and after one a couple same thing happened. This time I turned of the transponder in the air, and turned it back on. It reset and began working normal. I think I am going to check the harness and make sure its not working loose. When it went to fail, I noticed the transponder auto turned itself to off. When I tried to select alt or on it went back to off by itself. Traffic was still displaying so it was still receiving traffic. I checked GPS signal and I still had WAAS signal. I wish there was a datalog for the transponder or I could get into config mode when it was failed? Any suggestions?

Hey Dustin,

A friend with a G3X in his Arion Lighting had transponder issues that sound simliar. He eventually figured out his transponder was losing a high-integrity signal from his GPS. I believe he traced it to a wiring issue. I'll try to probe him a little bit to see if his issue really is similar to yours and if so, how he fixed it.

To clarify: he still had WAAS signal from the GPS, but it would lose integrity (RAIM). The transponder demands high-integrity.

EDIT: It sounds like his issue was different. His transponder never turned off, but it was not providing ADS-B out information. He recommends calling Garmin G3Xpert by phone or email. He gave me the contact info. PM me if you don't have it. I don't want to throw it up here as bot fodder.

Shadowrider

10-14-2019, 06:38 AM

Thanks Brian. All good info. To me it seemed related to when I was trying to land short and I planted it in. My GTX45R is mounted in the back and may got shook on landing. I wish the G3X had an MDC to record issues from LRU's that have errors.

Shadowrider

10-14-2019, 08:10 PM

Okay I think (fingers crossed) I figured out what happened to my transponder failing. I was suspecting something went wrong when I landed. I checked the transponder and it seemed to not be locked into the tray very firm. I could wiggle it quite a bit. I removed it and found that the allen stop screw was loose allowing the locking device to become loose. I could grab the transponder in the tray and move it in and out of the tray. I think this was happening when landing, causing the harness to not be seated fully. I tightened the locking mechanism to make sure the harness was fully seated and then tightened the allen set screw so it won't loosen up again. I am 90% sure this was the cause. Hopefully I can get out and do some flying this coming weekend after I am back from East Coast trip.

Dustin, just a heads up. I figure since I experience issues with this latching mech myself, maybe you should know as well. Since the floor of the tray is pretty flexible, that little catch may simpley push the floor down and it makes it not secure. Hopefully you caught your true issue and that is that. I have to reach up under my panel and apply upward pressure on the tray to truely secure my Xpdr.

Shadowrider

10-14-2019, 09:24 PM

Yes I did notice that. Mine is mounted vertical on the left side of the fuselage but the latch was very loose. I did tighten until the latch is seated snug, then removed and tightened set screw. At first I did it too tight and the base just pushed out. So, I backed it off some and tightened the set screw.

10-27-2019, 08:23 PM

Okay I thought I had the transponder figured out. Took it out and was able to get it to fail again. It failed when I purposely dropped the tail hard. I am still was getting slight movement of the transponder in the tray. With the tray mounted vertically and in the aft portion of the fuselage it still had slight play and I think is still getting bounced around. Its like when it clanks hard in the tray it fails. Decided to try and strap it also. I bought some velcro straps and strapped the transponder in the tray to help secure it for hard bumps. After doing this I went back out and I have a dozen off airport (grass and dirt strips next to runway) landings without the transponder failing. YEAH! The 40 hours is taking much longer than anticipated because of all the little tweaks. (My wife has been a trip and flying has been minimal with kiddos) I am not having any major problems, just fine tuning everything. I have my fuel map dialed into where I am happy with AFR and with EGTS now. I am running it rich to keep it on the safe side and burning a little extra fuel. Climb is very impressive. 2000fpm if you want to climb out steep. Cruise....well its what I suspected with the STI wing. Its draggy! I am seeing about 5.5 to 6gph and 105mph TAS. Defiantly not a cross country machine. Started playing with the shocks because they are really stiff. Temps are running very cool on the engine. In fact I can not even get oil temps warm. I have now covered almost 80% of my oil cooler to get temps up to 180. Last flight out I was able to get oil temps to 200F on a long high power climb. As soon as I level off temps come right down. In dropping the bottom of the cowl I think it has really increased the exit air and increased vacuum in cowl causing everything to run cool. Intake temps are looking good also. I am seeing 120F on takeoffs and climbs and then 100-110F on cruise. We are currently working on the cowl on my brothers STI and decided to go with a larger naca for the intercooler. We will compare intake temps and adjust as needed. I fly down to Nephi u14 and up to West Desert Air park UT9 to practice landings on the dirt. Takeoff's are easy. Tried holding the brakes and powering up. Tail started to come up and felt like it was going over, so I let off the brakes. It accelerates like a sports car! Mash the throttle and hold on. Landings are going to take a while. I am starting to get comfortable coming in slower. I did 10 landings with 5 knot wind and was consistently landing sub 300' I had a couple really short ones but I can see timing needs to be spot on to get really short. I have a field right by my house that is 600' long. My goal is to bring it into that field one day. I defiantly need lots of practice. The problem is it has a 5' fence on the one end that I will have to approach over. I need to do the math on how much it will reduce available landing distance? So far I enjoy flying slower 75mph seems to be the sweet spot. Flying above 90mph and it gets really noisy!

My g3x is listening to the rotax fadec which records time internally and how it is triggered cannot be changed from my understanding. That being said, mine seems to be going up faster than I would expect as well.

Shadowrider

11-01-2019, 06:03 PM

For engine time in the G3x I can selected oil pressure, or rpm, or variable rpm. It takes awhile for these engines to warm up and then my home airport I sit idle for 10-15 mins every flight. I think I am going to change it to not trigger engine time if its under 2000rpms???

11-02-2019, 05:06 PM

While I realize that my Continental IO-240 engine requires it more than the Rotax , I have found that preheating below 40 degrees keeps that ground sitting to a minimum waiting for my oil temp to reach the 75 degree minimum required for application of takeoff power. With this homemade preheater with parts from home depot aircraft supply my oil temp is about 85 degrees and the rest of the engine is toasty warm and ready for immediate flight after about a 2 hour preheat. Saves gas, saves engine gets you on your way without the ground stop. Bruce N199CL

11-02-2019, 07:24 PM

I wish the right number was what the left number is showing! What are most using for engine time? Seems like I spend a lot of time with the engine idling and warming up. Are most running engine time when engine is started or above a certain rpm? I am thinking I switch to above 2500rpm engine time to start counting. My oil is not even slightest dirty at 40 hours.

You might be concerned about the engine hours for the wrong reason. I found this explaination in an AOPA article:
The manufacturer's recommended TBO is based on the FAA definition of "time in service" as "the time from the moment an aircraft leaves the surface of the earth until it touches it at the next point of landing" (Federal Aviation Regulation Part 1).

The bottom line is aircraft & engine total time or TIS are based on the aircraft's flight hours. This is the number shown on the right on your screen. Your engine's TBO can be based on the TIS/flight time, not engine time. The engine time on the left is kind of a meaningless number unless you are renting the plane. As a A&P-IA I look at the tachometer on planes that have a recording tachometers for TIS. On digital panels I look at the "Total Time".

FYI I set my engine time to be triggered by oil pressure on my G3X and I ignore this number. Engine time is just like Hobbs time, which is what most flight schools do with rental plane. This is so they can charge the users for ALL the running time. Hobbs time has nothing to do with the legal TIS.

The G3X is programed to record "Total Hours" exactly as defined by the FAA, it uses a couple parameters to determine when the plane is flying.

Just like Bruce I preheat my IO-240 for a couple hours when it is below 50. Like he says, the oil is already warmed up and you can safely do the run up and take off without having to wait and waste fuel.

Rotax factory bases all their maintenance time intervals on total running time (Hobbs). This is per the Rotax-Owner website forums.

Phil thanks for that explanation. The aircraft I have always operated we go by flight time (time in the air) as you have said, for MX intervals.

So Jiott your saying oil changes at 50 hours of engine running, not flight time, is what rotax is saying though?

11-03-2019, 06:00 PM

Yes, Rotax 50 hr oil changes, 100 hr inspections, 200 hr carb inspections, 800/1000 hr gearbox inspections, etc. are all based on run times (Hobbs). This has been discussed many times on the Rotax-Owner forums, and the factory experts all seem to agree on Hobbs time.

Here are a couple pictures of my flying adventures. The last part of the 40 hrs phase one seemed to drag on so I decided to venture out a little bit. I had a 100nm restriction (leash) so I decided to venture down to Cedar Mountain. First time I did a couple passes and the winds where a little hard to tell what they where doing. It is because Cedar mountain sits fairly high so I think you get swirling winds. I mostly defaulted back to the garmin that was telling me winds where out of the north. Once I flew overtop I found the wind sock that confirmed northly winds. Being up on a mountain and the approach end is on a 1500' drop, the approach is a little tricky to determine your height but not bad. I landed and was surprised at how good of condition the runway was in. I had cell phone service so I did not feel to isolated. It did make me a little nervous shutting down the engine by myself though. Hopefully it would start again. Took a look around and decided to head back out. Flew a total of 3 hours that day. Decided that was fun and wanted to do more. I checked the distance and Mexican mountain was under 100nm from Provo, so I decided I may try it if conditions where right. I flew to Cedar mountain and landed. I also took lunch with me to eat. Pretty fun! Excited to go airplane camping. When I was at Cedar Mountain an aircraft flew overtop doing a pass and then came in and landed. It was a 182. I was impressed that it did just fine getting in. He said he was headed to Mexican mountain next. I felt better about going to Mexican Mountain knowing someone else was coming in behind me. Decided to give it a go. Flying into Mexcian Mountain, the most nervous part of flying there is knowing if you lose your engine, its not going to be good, and possible may not survive. Sure lots a places to land, but lots of times there is nowhere good to set it down. Mexican mountain was awesome. So quiet and no one around. I went exploring for a bit but decided to get back into the air to try and get the 40hrs burned off. I landed to the west and decided to takeoff to the East because there is more options if you lose and engine. The STI performed nicely getting out and I just mashed the throttle and climbed straight out of the canyon! As I was climbing out I heard the 182 starting approach in.

In the phase 1 the only test that had me a little nervous was loading it up to max gross and max aft CG. I left that test for the very last. I loaded the aircraft with 5lbs bags of stainless steel bags that my brother sells for reloading. (Cleaning brass) I put them into duffel bags. Looked like I was hauling something I shouldn't be. I needed 175 lbs in the passenger seat and 150lbs in the cargo and full fuel. Got it loaded and got a little nervous because I was surprised at how heavy the tail was. Triple checked the math, and it all checked out. T3 spring was bottomed out, so I had to jack the tail and tighten the spring 3-4 full turns. I could not pick the tail up. Didn't seem like the little elevators would have enough to get that tail in the air! Firewalled the throttle and manifold pressure hit 46". I guess I have just been so used to the aircraft being light and pinning me in the seat on takeoff, just didn't seem like we where moving very quickly. Take off was double maybe triple distance. Probably around 300-400' I was surprised at how the weight affected performance. I saw about 1000 fpm on takeoff and 500 fpm climbing. I decided to make sure it could still get to altitude so I took it up to 13500' I could defiantly feel the weight. Controls where much heavier and its not as responsive. Decided to try and stall it and see how it felt. Stalled much faster and took more rudder to keep it straight. First stall I just took it to buffet, nose lowered so I relaxed the controls. Second stall I decided to try and get it deep to see how it reacted. Was surprised to see how much the left wing dropped off and it fell to the left. I will say I defiantly like how it flies light versus heavy. Still manageable but not as fun to fly. I could compare it to my 1500 silverado pulling my boat. It pulls fine, but you know its back there and have to plan ahead or you can get yourself into trouble.

Originally I was going to do max gross weight test, then come back to unload the weight and finish the last 2 hrs I needed to do. I decided I wanted to get as much experience as I could being loaded heavy so I just decided to keep flying heavy. Autopilot gains needed to be adjusted to hold Altitude. I could for sure tell I was aft CG because she seemed to be more pitchy than normal. After flying for close to 2.5 hours and doing stalls and turns and climbs and decends I decided to head back. One test I also did, is you can go to the info page on the G3x and it shows glide ratio. Decided to see how she glides heavy. First test was with the wind. I was getting 10.1 glide with the wind. Then I turned 180 and was getting 7.5 into the wind. Decided probably 8.1 is pretty accurate. I am going to head to Ibex lake bed and I am going to try seeing how she flies with the prop stopped. Overall the glide is better than I had thought it would be. I headed back to Provo where I was told to report the right down wind for 13. I was asked if I could take 36 and the winds where calm. I was 1000agl about 1 mile south, figured I would just slip it in and I could accept. Power went to idle and I started down. I kicked the rudder pedals hard, like I usually do in a pretty aggressive slip. Nose dropped and right wind dropped hard. I didn't look back at the logs but I was very surprised to see how much airspeed I almost instantly lost. Tail also kicked hard to the side. Usually I just relax rudder and it will track back but I had to push opposite rudder to get it to come out of the slip. I was not expecting that. Once I got it out of the slip and airspeed control under control I had lost quite a bit of altitude.

Hopefully anyone who is reading this and has not done your Max gross weight test, just be ready for it to fly a lot different. I did not find anything unsafe, just very noticeable across the envelope the added weight. I am going to add into my POH to use caution when slipping when heavy to do it cautiously as it may react differently than expected. Overall I am glad to be done with phase 1. I have not painted my cowl yet, and I think I will wait until this winter. We are trying a little different Naca vent on my brothers and are going to compare intake temps. If we see similar numbers then I will paint. If his is intake temps are lower, I may change mine also. Intake temps: cooler the better!

Eddie the fun has begun! Took my youngest son and we went with a friend to the IBEX lakebed. I had no idea that you could have that much fun on a dry lakebed. A neighbor friend has a 172xp and I talked him into coming with. His son and my son are buddies so they had tons of fun kicking rocks. We setup cones and practiced takeoffs and landings. I was impressed with him as he is a brand new pilot was able to land his 172 in 600' and takeoff in 700'. We need to takeoff his wheel-pants and head to some more back country strips. I setup cones at the threshold, 300' 500' 750' and 1000' I was excited as I was able to consistently get under 300'. I need to spend some time and get the VG's on so I can approach 5mph slower. That should shorten it up some more. Takeoffs I was seeing about 120 to 110'. I was at half tanks and she still has more power in her. If I turned it up a bit more and got better on my technique I think I could be under 100' DA was about 5000'

We decided we are coming back to the lake bed with dirt bikes for the kids and make a camping trip with dirt bikes and airplanes!

We have been working on getting N53TF wired up (#2). Amazing how much I forgot, and have to lookup again. We are wiring them identical. Getting closer to powering it up. Almost time to run the Can-bus to each LRU and flip the switch.

I have been testing scoops on naca to see if airflow can be increased. I tested the naca for the cabin air by adding a scoop. The air velocity was increased from 50mph to 55mph out of the vent. I added to one side and not the other. I tested using a kestrel hand held weather station. So I tried applying a scoop to the Naca for the intercooler see if the temperature dropped at all. I need to review over the data logs but initially I am saying there was no drop. This could mean I have already max out possible airflow. I have not yet painted the cowl because I am waiting until we fly my brothers to compare temps. Once that happens then I will pull the cowl and paint it. I am also considering doing an annual at this time. Should be right around 100 hrs on the engine and I can reset the clock for the annual during winter when flying is slower.

One thing I don't like about the oratex is the staining. You can see from the pictures the exhaust stains the oratex and wax is not helping remove it or prevent it. Oddly enough Non-ethonal fuel stains it quicker than ethonal fuel, but they both will stain over time. Still curious if 100ll will stain? I wish I had a solution but have not come up with anything yet. I seemed to have tried everything. Only thing that works is laquor thinner. It removes some, but not all. It cant be good for the fabric though. I think I am going to contact Oratex directly and see if they have any suggestions.

The edge engine is running strong. Its fun to climb steep and hold on. Took my younger brother who wants to get his license up for his first lesson. Everyone's response has pretty much been the same. "Holy Cow!"

Tundra-lite users be careful! I got a bad shimmy last time landing. Felt like a flat tire. I did not realize the tail-wheel tension had loosened up. Jim states in his instructions you will get a shimmy if the tail is loose. I did not realize that it would loosen up over time, so check your instructions on how to set tension and make sure you tension does not go too loose. Other than that I have loved the Tundra lite. I don't ever lock the tail anymore, but its there if I need it.

This plane still makes me nervous flying, but I am starting to build more confidence.

Yeh Dustin, I see the yellow. I burn 100LL exclusively and when my wing fuel valve caused the leak I got the blue stain off with Isopropyl Alcohol. All of it. All I get down along the exhaust trail is a white residue that seemed to wash off pretty well with nothing more than the Oratex cleaner. I have pretty much run out of it so I will be testing something else now. And for those trying to rig your tail wheel correctly, call the wheel manufacture or understand that you can't use YouTube unless its your exact set up as I did. Now you know what I was experiencing Dustin. That wheel goes nuts when set up incorrectly. The Matco Wheel that comes with the Kit must have tension on the springs always where as the Scott style wheel needs slack, for those who still need to get there.

Shadowrider

12-11-2019, 08:55 AM

Thanks Eddie. Yeah the yellow staining does not come off with alcohol, acetone, gas, soap, ect. Very frustrating! As far as my tail wheel, the tundra lite is a full castering so no springs or cables. You just tighten the bearings down so it will not pivot around as easily. Takes 2 seconds, just didn't realized it had loosened up.

Dustin, if you don't mind answering, what is the cause of being nervous?
Is it just because it's new and you're building confidence in the airplane as you fly it more or is it because of the handling/power characteristics?

Okent,

I have been out of GA for over 15 years. The last 15 years I have been flying a part 25 aircraft, and we train for single engine takeoffs, approaches, landings, and figure single engine climb gradients, ect. Now only having one engine, I keep saying to myself....."what happens when I lose the only engine I have?" Suddenly I find myself on short final!

I am not nervous in the construction or flight characteristics of the aircraft, but more in the fact there is only one spinning thing on the nose and its not burning jet A. :)

With that being said it has been fun getting back into GA flying and learning some new skills.

I had an engine failure in a 210 last year and dead sticked it into a field. Upgraded to a Baron. I completely understand your concern over having one engine. That’s the biggest hurdle I have in getting my wife to let me build a kit Fox.

Dentist, I'm curious why you had to dead stick into a field? I thought all you twin flyers feel safe because you can keep going on one engine.

I have no personal knowledge on this, but I have heard of more than one twin engine pilots say that many twins cannot hold altitude with one engine out, to say nothing of the difficulty in maintaining control with only one engine at full power. Could it be that some (not all) twins give you a false sense of security? If I'm going to come down, I think I would rather be in a light single engine with good glide ratio and control-ala Kitfox. Just sayin-FWIW.

Shadowrider

12-17-2019, 12:01 PM

Jim you may have read it wrong, but he was saying he lost an engine in a 210 and dead-sticked the 210. Now he has a baron so that he has the safety of a twin. You are correct in thinking some times having a twin doesn't help engine outs. The saying we used to say is when one engine quites the other just takes you to the scene of the accident. Most twins including some turbo props give you no guarantee that you can takeoff let alone climb on one engine. Not saying they can't, but heavy, hot or high you can start looking for a place to land. I agree the kitfox goes soo slow, you increase your odds just by the fact you can go so slow.

Got a few goodies to try! Did not have time this week to put the VG's on, but looking forward to soon. I am going to put them closer to the leading edge like everyone who is getting good results. 2" is what I am thinking right now. Excited to try those. Corys kitfox is getting closer! We flipped the switch and got the Vertical power programed. Of course it was much easier than mine because I just transferred my setup to his. Since we wired his the same. We are having some can-bus problems but we should get those sorted out quickly. Trying to figure out how to transfer my setup from G3X touch to his because everything is wired the same. Trying to copy the config file to a SD card and load it on his. So far his is not seeing the config file. I am hoping that after I update his to the same version it should start to work. It would save hours of programming engine limits and alll the settings if I can get the config files to copy.

Okay now for what I am most excited about! I was skeptical of the balance master. I had spent over two days balancing my prop and getting it as perfect as I could. I used the Dynvibe G3x and went from .89 IPS to .05IPS. After seeing Larrys review and putting one on the Mangy Fox, I decided I wanted to give them a try. To get my prop balance I added close to 25 grams. I balanced mine at 5200 rpms because I figured this is where I will spend a lot of time. With the added weight 5200rpms was smooth. The problem I felt is when I powered back there was spots that where not as smooth. I called balanced mastered and ask them if I should leave the weight on because I had gotten mine balanced down to .05 ips. Chris told me that I need to remove all weights because they only help at a certain rpm, but will hurt it at others. He told me just put on the balance master and it will help through all ranges. I honestly felt it was going to be a snake oil and did not seem the amount of weight I had added that this would work. Mind you I was about to buy a dynavibe because I wanted to balance my plane every year and always keep my prop in balance. Went and flew it and I all can say is WOW! I can't believe I spent the hours I did balancing my prop when I could have done was put this silly thing on. It doesn't weigh much, maybe a pound, but did not seem like it had enough weight inside to help. I put it on and started my plane. As I was waiting for my engine to warm up I thought to myself, this stupid thing didn't help. My plane seem to have a hop up and down with the prop as I was waiting for the engine to hit 120F. Once I released the brakes and began to taxi it seemed about the same, but no better around 2000 rpms. Doing a runup still did not seem to be worth it and I was pretty skeptical. Once I rolled the power on and headed down the runway, I maybe for a split second felt vibration, but then immediately it went smooth. After I was up in the air I let go of the stick and could not believe how smooth the stick was. Defiantly much smoother than before. I went over to the practice area and tried different power settings. It was smooth through all power ranges. All I can say is I am sold. Pretty cool invention! Its pretty amazing how well it works. Through all power ranges its smooth. We are ordering another to go on my brothers Kitfox and will put it on his from the beginning. Like Larry said, this makes the Dynavibe obsolete.

So I wonder if the engine will always be rough on the ground/startup until you get up to take off RPM. OR if the balancer was just centering and will hold a reasonably good position for your next start up?

rcbif

01-06-2020, 05:44 AM

So I wonder if the engine will always be rough on the ground/startup until you get up to take off RPM.

That is what I would be concerned about. If the vibrations are worst than stock on startup and initial idle, you are going to be spending lots of accumulated time during warmup running the engine rough till the balancer takes effect.

So rough startup & smooth cruise, vs. average startup and nearly(?) perfect cruise via traditional balancing.

I would think engine cold would be the absolute worst time for it to have any imbalance.

Shadowrider

01-06-2020, 06:38 AM

Cruise is smoother, way smoother. All power ranges are smoother. I will take low frequency “hop” for a few mins to have it smooth through all ranges. Impact to engine is a lot less having it smoother every where else. When I was letting it warm up it was not really a vibration but about every second a hop felt through my squishy tires. When you hold the balance ring and you turn it you can here the mercury running around so I doubt it stays in any location on shutdown. Honestly it does not concern me one bit that it’s not as smooth at idle as before because it’s noticeably smoother through all ranges.

Ah, well that answers my questions as to how it works. I was trying to figure out how the thing floated on the back plate. Liquid, got it. I look forward to hearing more as you put a few more hours on it.

Thanks for the report

I am interested but am more than a little concerned about the initial warm-up vibration for "several minutes". I am reminded of a carb balance I was doing several years ago and the idle sync was way off. I of course had the upper & lower cowls off and was amazed and concerned as I observed the engine vibrating severely. It just about threw off an air cleaner and I was visualizing the internal carburetor float and needle parts jumping around; fuel coming out the vents. I shut it down and fixed things right away, not wanting to let it run this way for even a few minutes. By the way it was smooth at rpms above about 3000. If the Balance Master allows anywhere near this kind of idle vibration every time you start it up for several minutes I would personally remove it and stick with conventional balancing and carb synchronizing. I would be very interested to hear from several who have installed the BM and have gotten out of the cabin and stood by the engine idling with the cowls off right after starting and report what they see for several minutes. If the engine/accessories, carbs, air filters, etc. look like a visual blur with fuel spurting from the vents I think we would all want to know this.

Jim nothing like you are stating. No buzzing or vibrating, but more of a slight hop at 2000rpms that I didn't notice before. I was thinking of doing a before and after but didn't want to go to the effort it would have taken. I would not even call vibration but a hop. Like I said very low frequency. More probably to do with my NR spinner, as they don't track the truest. Nothing you would have even noticed other than I was paying close attention. All I can say is I would have to agree with Larry, they are amazing, and I don't think you will be disappointed. I think they will take it back minus shipping if you are not happy. We are ordering two more. One for my brothers kitfox and one for our powered parachute with a 582.

Regarding the Balance Master, it was reasonably enough priced, so I jumped in and got one too. I want to do some testing with it before commenting too much, and haven't been able to fly with it yet. I've got my own dynamic balance rig (ACES), and my assembly is balanced to 0.05 ips or less. One thing bothers me is the statement by Balance Masters that the assembly shouldn't be pre-balanced, as that can interfere with the operation of the Balance Master (which I'll call a BM :rolleyes:). Common sense tells me that's ridiculous... the BM has no way of telling that there is a weight installed to balance the assembly, or if the assembly is just well balanced all by itself. The BM is reacting to movement of the entire spinning mass that it is installed on. Of course if the assembly is well out of balance before installing a BM, the initial perceived improvement will be more evident and greater than if it was if well balanced to begin with. I'm not saying it is, but this could be a marketing strategy. Next, if you carefully watch the video test on BM's website, with a Rotax and a DynaVibe, you'll see that the balance with the BM is definitely improved with the BM (I'm assuming the assembly had not been dynamically balanced), but is not particularly good compared to a good dynamic balance job at other than high RPM, and it sometimes varies considerably going up & down through various RPMs. So, I'm interested to see what happens.

John I had the same thoughts you are having. I ran my prop close to what felt like 30 times with a g3x to get it as perfect as I could. (Mostly trying to set it up correctly) I ended up at .05ips. I thought the same thing why not leave the weights on and pre-balance it before? One thing to think about is when you are balancing dynamically you are only balancing at one rpm. I balanced mine at rpm at 5200. I felt after getting my to .05ips its was much smoother at 5200 but some rpms where not as smooth with the weight on. I had close to 20 grams. I called and asked BM and he said to remove the weights because they are not needed and some rpms they have found the weights to make it worse. I guess I can kind of understand that because my prop felt smooth at 5200 but it was worse are certain rpms. In fact in all my runs going through certain rpms I thought I screwed up the weights because it was worse on the g3x until it smoothed out at 5200. I was trying to find app to measure vibrations in the air so I could do a before and after in the air. All I can say is my prop is not only smoother at 5200 rpms with the BM then with my dynamically balanced prop that was dynamically balanced to 05ips.

I did watch the video on was not that impressed with the numbers and the video made me more skeptical. In fact when I was dynamically balancing mine I found the balance master but was not impressed. The only reason I bought it now was because of Larry and Mangy Fox review.

I will report back after a couple more flights if I am still liking it. I will be the first to admit I will pull it off if I feel it’s not as good as it was before.

This forum is sure costing me money. The last few purchases have been driven by discussions and/or recommendations read here. (Prop and balance master the last two. It'll be a few months for me before I can test them out.) Don't tell my wife where I get the ideas.

Curious to see others results with the balance master. We received our second balance master and we put it on our 582 powered parachute. It runs very smooth now!

I have been on the road, but I am back in town now as I have the next 2 weeks off. Going to get the VG's installed this week and go flight test them.

N53TF wiring is complete. Just waiting on an Ipad and landing lights and its complete. Programming went smooth and very fast. Because we wired both planes identical programming went very fast, and brain damage on the second STI was minimal. What took me what seemed like a week to program everyting on 33TF took about and hour on 53TF. I learned that you can just export your config file, then import the config file to the other G3X. G3x will not recognize config file unless both G3X versions are the same. It will then copy everything except calibration settings. Makes it very quick to setup. All my limits that I have been programming got transferred over. Cory only really had one mess up that took out the canbus. He had the wiring for the shield incorrect and the ground on the GMU wrong. Garmin is very helpful and he got all the troubleshooting taken care of pretty fast. Plan is to try and make sure the wiring is good by just running avionics a bunch, hoping if anything is going to die, it will die sooner than later. Getting ready for the first engine start and then its getting close. Windshield and doors are done. Turtle deck needs to be finished and flapperons need to be installed. Oh... and Cory needs his tail endorsement.:)

It ended up to be bad weather for a few days before I could get out and test the VGs. I went out yesterday quick before the next storm was due in. All I can say is WOW! The STI wing loves VGs. Stall speed was reduced almost 8-10mph. 10mph power off and 8mph with some power on. I was stalling at 34mph at 6000' Temp was 40F. Aircraft weight was 1124lbs. I put VGs on the horizontal stab and the along with the wing. Spacing between was done at the recommended spacing. On the STI wing I am 46" from the trailing edge to the front of the VGs. That works out to about 1.25" aft cord from leading edge or 2" from the leading edge on the top camber. It worked out well because that is also where the seam of the oratax overlaps. I was told that you really cant place them to close. I didn't want to go to much closer because it would be a bigger pain to clean the bugs off that we get so bad in the summer. Oh,.....and like others top speed is not reduced which is crazy to me. When you walk up and look at them it seems like a lot of parasite drag being created. Its hard to believe they work as good as they do.

With VGs I have alot more elevator control and does not run out of elevator like before. With power it will just settle in and you can really get a good AOA going. With VGs it does break harder but you are much slower. I am comfortable lowering my approach speed 5mph and with some more practice and some power 10mph I think is doable. Here is a screen shot of my Datalog showing when the stall breaks. If my math is correct that should be about 25' shorter landing distance reducing aproach speed by 5mph (speeds are in knots)

Anyone have experience with acrylic? We got some acrylic tubes and bent them for fuel sight gauges. Wondering if they will hold up better to Mogas?

Dustin,

Kitfox uses tygon tubing with a piece of brazing rod inside to hold the shape. There are about 8,000 versions of tygon, the one used by kitfox stays pliable over time and does not appear to be affected by gasoline (100LL or 91 octane corn free) other than becoming gradually darker over time - I have replaced the tygon at 5 year intervals to counteract the darkening tendency when I do the Rotax rubber replacement.

How would you attach to the barbed tank fittings? Is this acrylic brittle like most acrylic?

airlina

02-04-2020, 04:08 PM

The old Kitfox factory Skystar, used similiar tubes for the sight gauges on my Series 5. While I am not sure if they were acrylic, they were a miserable failure (breaking ang cracking over time) , with guys having tanks of fuel weeping into the fuselage at inapportune times. Luckily I found out about these failures before kit completion and retrofitted with my own version of what they sell with the current kits. Beware. Bruce N199CL

Re: sight gauges - I'm going to post some info on this subject on my build thread now also.

Shadowrider

02-04-2020, 04:41 PM

Clark thanks for the link. Interesting results. We have the ones that kitfox sells, just trying to see if there is something better so they don't discolor when running mogas.

Jiott we would just connect them using tygon tubing to the brass fittings.

Airlina yeah that would be bad, and that is what we are trying to avoid. Maybe I will give kitfox a call and see. We did find some glass and can make them out of glass but the acrylic seems stronger than the glass, at least when we bent them to test how strong they are the glass shattered pretty quick and the acrylic was bent way over before breaking.

Okay we have some acrylic tubes that we used to make some sight gauges sitting in a mason jar with ethonal 91, sitting in the sun to test how they hold up. But, for now I think we will just go with the stock ones and replace them when they discolor. I am approaching 100 hrs on my engine and its about time to tear it down and check it over. I have decided just to do an annual as I just got my repairman for my plane! The plan right now is I think I am going to trailer it home. I am going to change my exhaust out to the new upgrades exhaust system EP is working on. Should eliminate leaks and flow better. I am also going to change my exhaust to a straight out the back of the cowl like Cory's. Should keep the exhaust from staining the gear leg. I will fill in the hole in the cowl and take it to paint. Many have asked but how I like EP912STI. Is so much fun to fly and love the power. Pins you in the seat on takeoff and climbs like crazy. I had it out for my first off airport landings. I have landed dirt runways before but not the "bush." I am defiantly limited by landing distance. Amazing how a little float eats up landing distance. Now with the VGS I need to come in almost 10mph slower so I need to adjust for that. Loving the AOA as I do best by looking outside and just listening to the AOA beeping. It was a little bumpy so I was carrying a little speed. Landing distances are around 300' and takeoff less than 100'. Going out today and I will measure! ECU has been solid and tune has been spot on. I have had it up to 14500' (higher when I get o2) and down to 3000' and the tune has been spot on. Starts right up every-time hot or cold and idles smooth. Here are a few pictures of my recent adventures. Oh, and I got brave and went flying at night. Things I thought I wouldn't be doing when I got my ATP and starting flying turbines. Single engine, "EXPERIMENTAL", at night. :eek:

Good goin’, Dustin - your airplane looks beautiful! I don’t know when those pictures were taken, but it sure looks good to me... we’ve got about a foot of snow around here right now. I’m going to get over to Utah one of these days.

Awesome Dustin! Looks like you're having a blast!

Got some more flying in today. Getting slower on the approach speed but I feel like I need to come in steeper and slow it up a little more. Fun learning these new skills but defiantly challenging.

Really Nice Dustin. Your brother must be dying to get his done. Flying together is going to make having these planes such a blast for you two.

Yeah he is getting close. He needs to finish the turtle deck and then it’s about time to move it to the airport.

Hi Dustin, Interested in the tundra lite tailwheel. I was on their web site and they have two sizes for springs listed and two tire sizes. Just wondered what is best for the Kitfox? Your planes are exceptional. Jim

We went with the smaller tire. Smaller to keep your AOA the best for takeoff and landing.....tail the lowest.

Read up on all your progress. Super job. The space behind the instrument panel gets a bit crowded, eh? Lol. Enjoyed your videos a lot. :D

Update!

#2 Almost finished. Cory decided to paint the cowl and go with the new nace design. He ran on big naca versus two smaller naca's for the inter-cooler cooling. With the heat exchanger and dropping the bottom lip we are no longer concerned with water temps or oil temps. I completely have my oil cooler covered and the other day with OAT 60f I saw 205 on oil temps in the climb. Level flight was 190. Water temps and oil temps stay within 10degrees of each other so the heat exchanger seems to be pretty efficient. Now OATS are starting to warm up a bit I will start to uncover the oil cooler some.

With testing the acrylic fuel sight gauges in a mason jar filled with 91 and after 3 weeks they have become soft, so acrylic is NOT a good option.

Only thing left on #2 is the interior.

#1 Has come back to its birth place! After getting permission to land in the city park, talking to the fsdo office I decided against it. Then I decided to try the field next to my house. I actually went to the IBEX lake bed and setup a mock field with a fence to simulate landing in the feild by my house. The field by my house measured by me is 775'. I have a 5' fence to clear. I was figuring I would lose 180' landing distance having to clear the fence. So when I was at the lake bed I setup some whip flaps and streamer to see if my math was correct. I lost 175' clearing the flags and then stopping under 300' Total landing distance was 475 consistently. Its a grass field so I was going to go with a 1.6 factor, jet pilots will know what I am talking about. That gives me factored landing distance of 760'. Called and talked to the farmer and he was good with it. Well I ended up deciding against it because of my job. Decide because I would be coming in over the local school on approach, I did not want someone calling the FAA on me, not that I am doing anything wrong, but don't want any hassle. Bottom of the thread is the response from the FAA when asking about landing at the school. So I ended up just trailer it back home. With Scott's transport kit it was pretty non-eventful.

I am doing a condition inspection while I wait for the new exhaust from Edge Performance. Currently the exhaust is notorious for leaks. Thomas has resigned the exhaust that should flow better and seal better. Win win!
I have also decided to move my exhaust to exit out of the bottom of the cowl also. Like the looks better and should keep the gear leg clean. Much easier to install and remove the cowling also.

I did a leakdown check, and got an initial scare of low readings! These engines are really sensitive to TDC for accurate reading. Here are the results 83 83 83 84 PSI. Tested at 87 PSI and cold.

Last but not least upgrade is I bit the bullet and removed the baggage sack. Because we are one of the first STI's our instructions for the wings where not correct on the spacing of the flapperon control rod. They have now updated the instructions, but it caused the holes for the control rods to pass through the baggage sack to be off. So, to get by I just had to cut a slit. It looks cheap so kitfox had the triangle piece re-made for us. I was planning on just unstiching and sowing on the new piece with the baggage sack still installed but decided that would be a pain. Decided to remove the bagage sack. To re-install with the aircraft covered I am just going to install rivnuts. (Anyone reading this I would highly recommend nutplates or rivenuts so you can remove the baggage floor board if you ever need to.) With the baggage floor board out, I decided to extend the extended baggage! Really wanted to make it so a full long barrel rifle could fit in the baggage. Sowed a zipper and a 14" pocket. This is so I can sit a gun case and put the end of the barrel down in the pocket. The pocket is to make sure nothing ends up in the tail of the aircraft. Most of the time it will stayed zipped closed, unless we put some rifles in it.

I am working on getting my cowling painting, and painting the stained oratex. Aerographics is working on some decals and some stripe renderings and then it will be time to put her back together and at that point call it complete!

There are too many variables for us to provide a comprehensive list of possible issues affecting a safe landing, or takeoff, in a park. Therefore, I will attempt to answer in a very general manner.

If a person lands on private property, we consider it a land use issue. If they have/have not received permission to use the land, it is a matter between the landowner, police, and town.

However, we do have safety concerns and authority over the pilot and aircraft that is used during the operation. The pilot has all the obligations and responsibility when landing as with any other flight. Therefore, all sections of the regulations apply wherever an aircraft may take-off or land.

The location is not remote, and has the potential to affect non-participants, creating a hazard to persons or property on the surface. The pilot and others should consider prior to flight, and be prepared for the armchair corner backing that will take place if there is a mishap.

A few issues of the issues would be:
How was the approach/departure path determined to be safe?
How was the landing surface determined to be suitable for the operation?
What are the performance figures for the aircraft during the operation?
Is the aircraft in a condition for safe flight?
What is the weather, and how would it affect the operation?
Is the pilot capable of performing the needed standards, and should it be performed, for the conditions?
How was the site secured to prevent non-participants from entering during the operations?
Who was authorized to be on site during the operation, and why?
When was the operation expected to take place, and why?

The list can go on-and-on.

We do not approve, accept, or endorse this type of operation. Any liability falls back on the pilot, land owner, and those who may have authorized the operation.

Getting ready to paint cowl! Wish me luck! Filled in the hole from the exhaust. One more sanding and I think its good enough for me. We had a painter paint Cory's cowl and it turned out great but charged us alot of money. So I will find out if it was worth it??

Hi Dustin
your using silver paint so your not likely to have my problem. Because I used Yellow paint I used white primer to brighten it up. I layed the white primer down over my cowl that looked just as yours does now with the grey primer cowhide print. In the right light I can still see how the paint is slightly different because the dark primer splotches change the light. Of course there are so many variables that impact the paint transparency but maybe just lay a grey primer to cover all the gel coat? Good luck on the painting. Im so looking forward to seeing the two of them flying together. Don't hold out on us with those pics and video.

Thanks Eddie. I have used the same paint on my stand up jet skis and coverage seemed to be good. Without a paint booth it’s hard to control all the variables though. Hoping that painting early morning, early spring, the air will be clear and the paint gods will smile upon me🙂

Hey Dustin

Is the small NACA duct on the right lower cowl your engine intake? I’m thinking of putting a cold air intake on my 912iS and trying to figure out how to mount a filter and plumb in to the throttle body. Did you fabricate the NACA or buy one and if so where did you purchase it?

Thanks.

Shadowrider

03-21-2020, 10:54 PM

Yes my filter sits right up next to it. Its a naca I bought from kitfox. Its the same naca that you use for cabin air. Because of the shape of the cowl I had to heat it with a heat gun and melt it to form to the cowling.

Frontier Fox

03-22-2020, 08:43 PM

Curious how you mounted the filter. It would seam that it would need to be enclosed in a filter housing then a flexible tube to the throttle body. My throttle body is 2 3/8” outside diameter, the NACA is 2” outside diameter. Just wondering if there would be enough air flow.
Thanks for the info.

Mine will be different because my filter just hooks right to the turbo. Here is one photo from my build log.

Paint the Cowl.....check!

First go at it went not as well as I hope. Paint had to many flaws so I wet sanded it and tried again. I think silver metallic is one of the hardest to paint. Very challenging not to get "tiger stripes" but it turned out pretty good.
Its always a good day when a box from Edge performance shows up. The new exhaust is quite impressive. Thomas parts are always top notch. Running very tight tolerances on things and I am hoping this takes care of the exhaust leaks. Slightly larger, but I don't think by enough to see a noticeable difference. I think I will see the difference if exhaust does not leak it will make things more efficient. The mounting flanges are bigger which should also help. The slip joints tolerance are much tighter and I think should do the trick.

My brother got his livery done.....well mostly done. I didn't think it would come out as well as it did. He used knife-less tape and rolls of vinyl. I went aerographics route but wishing I did the same as him. May just have to down the road. Interior is going in, and then he is pretty much finished up. Waiting on exhaust from Edge to switch out to the new version then we need to do some ground runs.

Finished condition inspection, and got new exhaust installed. In the process I discovered the egt on #2 is too close to the oil filter. I have to say Edge performance makes great products and on top of that have great customer support. They are making the correction and will send out new updated header. So something that had bother me from the beginning is how the exhaust is staining the Oratex. I tried every cleaner and considered every option. Oratex was will to replace all the stained oratex, but I was not quite willing to recover to have the same problem. So the best solution I came up with was painting oratex to cover the stains and protect it from future staining. On Corys we extended the exhaust to try and get it away from the fabric, and are going to try and ceramic coat the fabric. I decided to move my exhaust also, mostly because it looks better I think but should also help keep things clean.

I checked the weather on Saturday and looked like I had a window to get it painted. I am using a poly urethane single stage paint. I have painted some test fabric and its been on for over a month. It seems to have the flex needed and it cleans off so hoping this works. I even taped a piece of painted fabric to the gear leg where its staining and flew for a couple hours. Stains came off the painted section with some simple green. I was nervous about getting over-spray on the plane so I did my best to cover the plane up. I started to painting and weather turned and started to snow. Luckily my other brother Trevor, (two brothers live next to me) came and helped hold a sheet of cardboard until the paint flashed. I was sweating bullets! Turned out good and paint came out a really good match. I don't enjoy painting because it is very stressful. The best part of painting is taking the tape off! Time to start putting it back together and get it back up in the air!

Man Dustin that is beautiful. I don't understand "knifeless tape, vinyl roll" though. So, Im curious. In the end, will your aerographics look the same?

Shadowrider

03-29-2020, 05:11 PM

Thanks Eddie. Mine will have a stripe but I didn’t have the vision to do all the details Cory did so stripe is pretty simple. Knifeless tape you basically lay the design out with small tape with a wire in it. Then you lay a sheet of vinyl overtop. Then you pull the wire and it cuts it. Bunch of videos on YouTube. Pretty cool stuff.

Shoot! Looks like I am waiting on parts to get back flying. Shock on T3 didn't last long. Seal is bad and leaked the oil out. Called Alaska airframes and they said they would try and warranty it and they would call me back. Never heard from them so I called and they have a message that they are shut down. Found the same shock on amazon and ebay. Anyone wondering its Gusty 165mm 1000lbs spring. Just waiting for shipping. I ended up getting one of Ebay because amazon says 2day prime shipping will take 2 weeks.

Hi Dustin
Are you not just going to replace the O-rings?

Shadowrider

04-01-2020, 09:25 AM

I thought about rebuilding it but these shocks are cheap china shocks that are like 50$. I think there is something also wrong with the internal valve. By the time I get the new seals and dissemble and refill with oil just decided to buy a new one. Thought about sourcing a fox air shock, but I actually prefer a spring because they are pretty failsafe. Blow a seal like I did you still have spring, just no rebound control. I noticed it on my last landing as it was springee on the tail.

Going to look at mine, I know they upgrade from the original, just don't know when. Thanks for the heads up.

When I spoke to them on the phone they said if the sale manager decides not to warranty the shock they are only 60$. They work good for what they are.....until they leak😬

That's good info Dustin. It looks like the Amazon unit doesn't have a second "check" nut. Does the one from eBay?

Shadowrider

04-01-2020, 07:56 PM

Yeah I noticed that. No the eBay one does not look like it does either but ebay pictures are not that reliable. The eBay one is only 750lbs spring so I am hoping I can transfer over spring an possibly lock nuts from t3 one. I am really not worried about only 1 lock nut because with the tension in the spring it’s not going anywhere. I will report back if the eBay one works.

Shadowrider

04-05-2020, 06:50 PM

New shock arrived and it works. Spring from the T3 (1000lbs) transferred over to the new one that had a 750lbs. Hopefully this one last longer!

Fingers crossed that final inspection happens in a week. Scheduled for the 5th. In the meantime Cory has been working on small odds and end jobs. We where not satisfied with the supplied wood stall fences because ours where severely warped. I am currently not running any. Cory has been determined to figure out this carbon fiber stuff. I think this time around he has got it figured out. Switched to infusion and it worked better. I have been flying mine quite a bit. Decided to fly down to the IBEX lake bed and go camping with the family. It was fun giving rides. Lost track around 20 on how many landings I did. One lucky kid got to ride down and the wife brought the others in the truck and dirtbikes. Could not get much funnier than dirt biking and airplane flying! First night she spend the night outside. https://lh3.googleusercontent.com/IiKknr_g0w3t99zD0SI5rsx7vshug3QOLpjd7G9oWlgTR3pfCz ihoZ2Y8q07pc7WUN4eEO-ZVAHZgDm9lsrZe28Yln1V_ieZsnVagYv4WOUTZvt1CPl17zM8x PeAfAO_tj-vV9jUjjTVzkmjOtPJQ3DqJLF_OMXUh8gaG31CeGEdp1Xj5cs4_ k39vOKaP_EoGdGdSGu-z4c3WLL3OrzAjYS_aOyzapkkA2404euleMsPiuRyR8h28-N1jL4Z4S9K1kLYQ2m4mSxFrqP2gSeL_QPqFofm0LSAnpKxZUty YI0mZCLxDPpK9JPpn6fm-B2RVofTtXz9kXGW-kJQahfFj0puX5QgZSNYRG1N1BhGn4RDkhl070VbHtdzMie3nGk IYa4I7Iq83jdsmtcYInRNs_Tcj_sm_yDydcSSuJ01VV2O3bkz5 ENPS8dp-bYz-W4h8ssKGYZ73xjZAHSS6IrlvwppmMlzj2ECCxdrAENhsKW_FI6 uz5xV0RPGHjSQLO6Gfzns_MlT_5ycggBrreLUQMd96dhgGkwqT FvVLTrDwKec48PNUuJLvsdvhV18rYwfLjmXfGbmGRjRqvlpb2X bwSFpnkaSoToLN4vTV2_8VrGrqv0_Un6fw-zWpnhhSA0RDp4Yy8DdI93gM4aeMlqJpSqd9K6xLfxYRLZrdBuF gJ4eupiZasAnphgjMOPnqwWGy3cZ8hqQRkhA3EF4Bw0b27B2DT cX8cuRBjWjH9KtHiGjfsXGoUT2WQ8d=w1382-h1036-no

Looks like a great time Dustin. Thanks for posting the pics. I stole your idea of the under wing lights for my SuperSTOL. Looks great!

Dustin, that looks fantastic all lit up on the lake bed. I have been prepared to camp with mine for some time but Covid has my destination down in Barrego Springs closed down. As you can imagine, CA doesn't have a lot of options for camping in the back country. Ill get it done hopefully in the fall. Im certainly going to get some camping in on Catalina Island as well, as soon as the stars align.

Clark I am exciting for you. Your fiends with Terry correct? Excited for you to fly it with edge motor. They pull hard and throw you back in the seat on takeoff.

Eddie Catilina would be awesome! You will have to post some pictures. I am hoping to get out to some back country strips next week.

Dustin, yes, I'm friends with Terry. We just got the wings back on his Kitfox. He's moving along working on his panel now waiting for the engine. Yes, I've got an Edge Black Edition Epex 300Ti coming soon for my SuperSTOL. Can't wait! Terry and I will be covering my fuselage in the next week or so. We're living vicariously through you and others videos and stories. Thanks for posting your adventures!

Well bad news.....we failed inspection. Unfortunately the DAR I used for 33TF retired. We have been waiting for a new DAR to be hired to get N53TF inspected. He was hired recently by the FAA, or appointed, and the day before inspection we where informed two FAA representatives would be showing up with the DAR to watch over his shoulder. DAR told Cory to plan the inspection to take a long time because the previous day it took half a day to inspect a plane that was already flying. Sorry if the DAR happens to read this, don't take it personal, but I feel he was nit picking items. I guess I understand his position, that he felt like he had to because the FAA was present. He failed safety wire because the end was not bent over which could cut you? Safety wire had to much space between the bolt and and was not twisted to "spec". Biggest item he did not like was how we passed the brake lines through the fuselage. He wanted them to pass through fabric like manual shows. Cory argued that was for the grove gear and not the Cabane gear and some details are not outlined specifically. Ultimately he lost and was written up and will not be passed until we comply. I completely dis-agree with how he wants us to run the brake lines through the fabric. Grove gear it works fine but not as good on the cabane gear. By doing it through the fabric it will change the pivot point of the brake line and will have much more moment in the brake line. We went through the fuselage and down the back of the gear to keep the brake line as close to the pivot point of the landing gear attachment point to reduce any stress on the brake line. That is how I did it on mine and its been working great. My brake line is sleeved with heat shrink and then secured to the fuselage in the hold that it passes through with black RTV making it somewhat rigid to the frame. The brake line then travels down the gear leg to the caliper. I tested this when the gear was on and moved the gear. There is very little travel of the gear at the pivot point so there is no stress or movement on the brake line. I then included extra brake line in the gear leg so if there was to be stress or pulled it would pull excess from the gear leg. DAR did not like that. He wants it in the fabric. Cory did his best on discussing why we dont want to do this. We are working on some possible solutions that will hopefully satisfy the DAR.

Now the good news! N33TF is running and flying great! Been to the backcountry of Utah camping and I will post some photos later!
