The 422's aren't enough servo power for this plane. You will need 70 oz/in at least. 422's are around 42 oz in. The surfaces are much larger and deflect a lot more than standard planes. I'm running JR 4721 on the rudder (119 oz in) and hitec 545 (5 poles) on the ailerons and elevators.
Had a chance to get Rob Sarlan (NE IMAC director) to put this through the paces yesterday. If this didn't overstress it then anything I do won't much matter. He should be purchasing one soon. He did say it was really a surprise to fly. This was just after flying his new RadioCraft 42% Extra (what a beautiful plane).
