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

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?
