I am flying an Aeromaster now with a ST 61 - I didn't measure the throws but I can check. I always put in as much rudder as I can get and about 1/2 up and down on elevator and at least that much on ailerons. The original kit used bellcranks and one servo for ailerons, I would change that is possible to two separte servos but it works good as-is. Really a nice flying plane,
