How much torque is enough?

I'm wanting to use a mico/mini servo to operate a throttle on a glow engine (.91 FS) to offset the weight of a high torque servo for the rudder.

What is the minimum torque you think would be required to run a standard cable/nylon sleeve pushrod for a throttle? The ones I've seen are about 15-17 oz/in torque does that sound about right?

RE: How much torque is enough?

As long as your linkages don't bind you can use virtually any servo on a throttle assembly. Depending on the linkage you'll only need half that in torque to actually move it.

You should be able to use any servo for throttle. Make sure that you use the inside hole on the servo.
