I think I'm in the right place for this... My other choice was the beginners forum. I'm not a beginner, but I have what might be considered to be a beginner question. Why does differential in the ailerons help correct adverse yaw? I've never bothered to find the answer to this as I just coordinate rudder into my turns, but since I'm going to be doing some "depot level" maintenance on my 1/4 scale Cub, I'm considering adding differential. Also, if I do, how much should I add? Or is that dependant on the airframe? For an idea of the amount of yaw I deal with, at half throttle, banked about 60 degrees with no rudder input, the plane will nearly stall before it will turn. Since I always get quality answers here, I'll thank you all in advance.
