Kitfox 4 left turning tendencies.

It could have been me that said I used a piece of aluminum and double sided automotive trim tape. It is now 5 years and 700 hours and that trim tab is still there with no sign of coming loose.

Can you resend the pic and if not through the forum, due to technical difficulties, could you send them to my email. jayandpamela@yahoo.com
Awesome!! Thanks for responding to that thread.

Here is something else to look at. Are your rudder pedals even when the rudder is straight. I had a Kifox 1 that had a little twist in one set of rudder pedals. I would naturally try to keep my feet even, and that was actually giving a slight bit of rudder. Adjusted the cable length, and then all was well. Now the passenger would have had to deal with it if he was doing the flying.... JImChuk

Pedals are good. They originally had never been gusseted and the right side pedal had bent on the cross tube. I removed both assemblies and replaced the right side cross tube with 3/4 .058 tube instead of the thin mess. Gusseted all the pedals with Tig welded gussets instead of the rivet/ epoxy AD. Super strong and they are all even. That was a while ago. Going extra on the trim tab got it to quit yawing so much. I am going to move trim tab down below the stab centerline on the rudder and see if I can get more effect from the airstream. I think where it's at it has dead airflow. Same thing on the wings for down force on the drag cars I build. If the wing is under or before the airflow, you get little to no effect. Teddy

My rudder trim tab is a piece of thin aluminum 4x6. It is bent at 2", so 2" sticks to the fabric with double sided 3M foam auto trim tape, leaving 2"x 6" bent in the wind. I also put a piece of contoured wood over the part stuck to the fabric to make it look better, but I'm not sure that was successful. The vertical center of the trim tab is located 29" up from the bottom of the rudder (SS7).

Thank you Jim. Did you move it from top to bottom during testing or did you put it on and leave it?

Did you try tightening up the spring on the right rudder pedal. Just a little bit might get you the right yaw your looking for.
