Mark, Are we talking the same thing here? Don't you have a huge trim tab permanently set on your rudder which will correct center your ball in flight? Maybe I misread what Joe was talking about but if you have no trim tab mounted to your rudder, which I do not, you must keep left rudder input to keep the ball straight. If you have a trim tab mounted to your rudder and have it adjusted properly, then of course you can fly with your feet off the pedals. Did I miss something here?
