Re: Joe Ruscito's Kitfox S7 Build
Still lots more tasks to come! I’m getting excited though!
Ill tell you as others have said the G3X system was pretty straight forward once you get the hang of it. And garmin technical support is exceptional! And when you’re done wiring they’ve made configuration so user friendly you barely need the manual. Really a well designed system imho.
Re: Joe Ruscito's Kitfox S7 Build
Is there a small plate under the GA35? Looks like it only has two screws in it now. Will it just sit on top of the baggage sack?
Thanks
Re: Joe Ruscito's Kitfox S7 Build
No plate. I know its hard to see in the pictures but two adel clamps up front bolted right to the GPS and then two Al tubes with the ends flattened and bent in the back. The tubes are bolted to the GPS and adel clamped to the frame on the other end. Its very rigid. Ill melt holes in the cargo sack and it will sit on top. I didn't see a need for the plate/weight.

First engine run yesterday! Feeling like Im nearing the finish line! Also had my tech adviser out yesterday and he gave the thumbs up on work to date. One minor cable routing suggestion, to get a bit more separation between fuel valve and wire harness. Added a standoff to address. Some pictures of my progress in the last few weeks. Had the wings on briefly to finish the turtle deck and lift struts.

All went well with the engine run except I noticed a steady fuel pressure of 37.8 psi once the engine was running. Before engine start I had a full 43 psi. Im starting with just the main pump turned on and ran the test with only the main pump (not both). Should I be running both? Im using a UMA pressure sensor. Being the first start I briefly brought the power up to 2500 once I confirmed I had oil pressure (to switch lanes) and then ran for 2 mins at 2000 before shutting down. All else was in the green and the system voltage was steady at 14.7.
Any thoughts on why I might be seeing the low pressure?
Thanks!
Re: Joe Ruscito's Kitfox S7 Build
Joe
I'm asking for my own knowledge: is the fuel pump supposed to put out a constant pressure or is it controlled by the ECU and after starting it varies the pressure to whatever it requires?

Re: Joe Ruscito's Kitfox S7 Build
Rick, that I do not know. I simply know that what I was seeing was below the normal operating min that was called out in the owners manual.
Re: Joe Ruscito's Kitfox S7 Build
I know its apples to oranges, but for what its worth my fuel PSI drops 5 psi when my engine starts. My fuel pressure ramps up above 2500 rpm.
Re: Joe Ruscito's Kitfox S7 Build
I’ll check that next time I run. Next run will be at a higher rpm. And I’ll check the other pump this one only went above 2500 for 5-10 seconds
