On my rascal I don't have any aileron to rudder mixing. It isn't needed. It's electric with a ten cell at 70 amps brushless. Goes vertical at under half throttle but cruises beautiful. It flies so much better than a cub in my opinion. My other one had a os120 and flew very well on that engine. Was going to put a asp160 in it but a friend talked me out of it he other rascal
