I have a 92 model Kitfox 4 that I'm currently flying every day possible. It has 80 horse 912 and 3 blade Warp, taper tip. No bad habits at all except for the dreaded left turning tendencies. No issues out of the ordinary anywhere but cruise. 80-85 mph and if you let go of the pedals it will seriously yaw to the left. Wind direction will obviously make it better or worse. I do have a bendable trim tab and it's bent pretty good. Worst yawing is with a quartering tailwind from the left. I have played with it in different wind directions and for the most part it's always there. Should I maybe do a bigger tab, or maybe consider a tick of right thrust in the engine? Tab is about 3x5 and bent probably 35-45 degrees now. Headwind from the right and it's pretty good. Thanks!
