STOP BRACKET SHOULD NOT BE USED AS THE PRIMARY

MEANS OF LIMITING MOTION. THE AIRFRAME'S STOPS

SHOULD LIMIT MOTION BEFORE THE SERVO CRANK ARM CONTACTS THE STOP BRACKET.

FOR BEST AUTOPILOT PERFORMANCE, ANGULAR TRAVEL

OF THE GSA28 SHOULD BE MAXIMIZED. AIRCRAFT

ATTACHMENT POINT, SERVO ATTACHMENT POINT,

ONLY. DEVIATING FROM THIS GUIDANCE IN EFFORT TO

INCREASE SERVO TRAVEL IS PERMISSIBLE PROVIDED

IT DOES NOT RESULT IN AN OVER-CENTER CONDITION.

TO REDUCE THE RISK OF AN OVER-CENTER CONDITION

IT IS HIGHLY RECOMME
