Stabilizer trim jack-screw and motor.

[Maverick]

One of the things that I didn't get with the series 5 kit I purchased is the electric jack-screw. Does anyone know of a suitable substitute I could research? Or, if you know whether the current series has the same type of trim system as the 5 ?

[PapuaPilot]

I think they are the same. It's best to call the factory, Deb McBean will have the answer for you.

[PapuaPilot]

I would keep looking in the build manual. They have the complete manual online.

I have the builders manual for my series seven and it does not have those pages, hopefully john will send them to me as the link is copyrighted and not able to print pages. I really do appreciate your help..

In-cockpit trim indication is an option available from Kitfox.

If you look here http://www.kitfoxaircraft.com/images/PDF/KApartscat-rev7-7-17.pdf on page seventeen of their catalog, you will find the trim kit mentioned.:)

I did not put in the cockpit indicator. I have a friend that had it and said his seemed fiddly and not all that reliable. He also pointed out that you only need to know the position before takeoff. Other wise you apply trim as needed to fly the plane. In 2003 when I first flew our Ktifox it was easy for me to turn around and look at the position of the stabilizer. 14 years later I am not as limber so as to make that turn to look but it is still doable. I am considering a switch of some sort in the tail and an indicator light for my "old age".

I did not install the trim indicator in my SS7 and have gotten along quite well without it. As was said in the previous post, you only need to know the position prior to takeoff. My routine is to look at the trim position just prior to getting in the airplane and set it properly if needed. Another method that works quite well is while taxiiing push the Nose DN switch until the stick stops moving, or for about 10 seconds (this assures full Nose DN position). Then push Nose UP for two seconds, which puts the trim in perfect takeoff position. Actually takeoff position is not very fussy and anything near the perfect position works just fine.

[jiott]

FWIW I have taken off several times with the trim in full Nose UP position due to sloppy use of checklist. It lets you know right away as you try to raise the tail; requires much more forward stick pressure. A normal takeoff is still easily done, just needs a lot of forward stick as you correct the trim in flight.

Jim,

You’re a 45 minute Flight from Homedale. Run down and chat with John.

If you are going to put in a digital panel you have the option of having trim indication on your screen. I just upgraded mine to show elevator trim. The Kitfox factory sells a kit for this, which has a potentiometer and mounting bracket and was very easy to install. Mine is very accurate, where as the cable feed back that came with the plane lags when you reverse directions.
