Hey Tim,
Those throws sound OK. I can't remember exactly what the throws were on my Aurora. When in doubt, my approach has been to have a bit more throw with plenty of exponential or just use dual rates (I barely use dual rates any more, myself). I don't even measure the throws, just make sure that both ailerons match (and both elevators). I don't remember having any differential in my Aurora ailerons and very little pitch mixing with rudder (if any). I may still have the Aurora set-up on my transmitter.
Good luck and have fun!!
Will
