Sam,

Are you sure that the 133 oz inch servo is enough for the high drag the flaps get? I am using HS7955TG servos on all my control surfaces and your Corsair isn't that much smaller than mine. The 7955's are 333 oz inch. I don't know your set up but mine are 2 servos per side for the flaps. The 2 inner flaps run off one and the larger outside flap runs off another one. How is yours set up? If your just running one flap I still think I'd go with a little heavier servo.

JMHO,

Barry
