Tim, These planes do not take much to put them through maneuvers. Remember, these things fly fast compared to modern pattern planes and have less drag. If you have a Tx that has expo. on it... dial in some for your set up and go from there till you get a feel for this plane. To much throw will cause these planes to be very twitchy and unpredictable. I would say 8 degrees for low and 12 degrees for high would be good for min./max throws on the Aurora. The reason I say 12 max is when the plane is slowed down.... sometimes you need that little extra depending on conditions. The rudder is the only control surface that uses a good amount of throw on these old birds. Everything else is overkill and most likely cause a bad "snap" or sudden roll out.
