Moving flight controls with a stepper motor.

Piggermortis:
I have a throttle and stick control that I want to move when my autopilot kicks on and will move the controls accordingly. Can anyone recommend a stepper motor for this?

You can certainly do better than this! Is this for a 474 or a toy? The throttles in planes I have seen use either a lever or a rod to push/pull. How would you attach a stepper motor to this?

If the autopilot "kicks on", why doesn't it control these things?
