i set my elevators to 12° aka 1 inch and my ailerons to 7/8 inch rudder i don't know ?
thats low rate for imac and for middle rate enough elevator for a square loop and enough aileron for rolling 1 role per sec and enough rudder for a nice knife edge loop for imac and high rate full deflection because i like to do crazy things with my plane

thats how my WH extra special is set up i need many flights to get the dialed in and I'm sure some of the rate will get tweaked
