I ran Hitec 81's which are 36 oz torque, BUT I ran one servo in the center of the wing. If you are running two servos out in the wing ON THE UPPER SIDE, you might get away with it, but PRO servos are 22 ounce of torque and it would be more power than what I ran. Then again I ran Norvel 25's and you're upping the power.

Me, I'd order the pro versions and use the regular one for throttle control. The darn Pro versions are listed cheaper at Tower anyways so why not?
