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
