The autopilot uses two stepper/servo units. One is placed beneath the pilot’s seat and uses a pushrod to move the Control Column forward & aft for pitch control. The other goes back by the ends of the main roll pushrods and is actually only pushing on the Left flaperon assembly for roll control. This page documents the creation of those pushrods. The remaining steps on this page are not applicable since the A/P is being installed on initial build instead of being retrofit.
