I fixed the turn

[Wheels]

I fixed the turn on the Kitfox with a trim tab.
40 degrees on the tab.
used double sided adhesive to secure for the test.
Plane flys hands and feet off at cruise.
May just leave it alone if the adhesive holds like I think it is.
Or should I rivet it to the tail structure.
tried to upload some pix, couldn't figure it out.

I used Jim Ott's design and used double sided tape. Its been there for 3 years and no sign of moving.

Mines been there 5 years with no sign of loosening. Use the 3M double sided tape sold for automotive trim.

Same 3M double sided tape as Jim - auto trim high strength


Been there for about 3 years



I think it would have to take the fabric skin with to fall off


FYI - Mounted mine on the right side or the rudder like tube and fabric certificated planes often do - nice thing about this it the tab does not stick way out in the airstream - if you look at it from behind the aircraft, 75% of the bend is right behind the rudder tube and little sticks out on the left side.

So what does this fix? Is there a turning tendency? Is this something that could be designed into the tail before covering? I'm out of the know on this one.

Most planes have some P factor or some out of trim condition during one or more flight speeds. A trim tab in most planes is an easy fix. There are of course many ways to adjust a roll rate, yaw or pitch condition mechanically. I"m not an expert and I did not build my plane but I always had a left yaw tendency. It was actually pronounced. I had to keep my right foot in it at cruise and it was tiring.

I tried washout adjustment, I tried shimming the engine mounts on the opposite side while the engine was off for an oil seal and water pump work. I could have adjusted ailerons etc. I finally added a trim tab. It took twenty minutes to install. the plane flies like a dream. I"m too stupid to upload pix. Send me your Email address and I"ll send you pix if your interested.
