BearCat:

Think back to your ARF, and the ailerons. Remember the wires that stuck out of the wing near the center where the aileron servo connected to operate the ailerons? Those were the ends of the torque rods.

With full span ailerons wire torque rods are fine, they're not long enough to twist and wind like a torsion bar.

With the scale "Barn door" ailerons of the Cub, the wire would be long enough to give a problem, but a CF tube, around 1/8" outside would be all you needed.

Definitely less expensive than two mini servos, and lighter than the stock wire and bell crank system. More precise too.

Minn, come on in here and give us one of your famous drawings, please.
