HS-81 aileron servos
MTT, you're probably right. I considered the HS-81, but something led me on to the HS-85. I think the 81 uses plastic bushings, whereas the 85 has BB top, which I thought would be more appropriate for getting back to neutral. I regard the 81 as a great throttle servo. But torque-wise, the 81's 32 oz-in per surface on a Contender wing should be no problem.
