trev130eng Posted April 7, 2012 Share Posted April 7, 2012 Had an identical problem very recently. Flt computer or amplifier if it is both sides. Problem solved by finding elevator trim tab problem. No lubrication for years causing very slow tab operation from autopilot command. If its not electrical maybe trim tab rigging or elevator trim relays.
