(ALL VERSIONS)
BELL CRANK MODIFICATION, RV-4/8
NOTES:
FOR BEST AUTOPILOT PERFORMANCE, ANGULAR TRAVEL OF THE GSA28 SHOULD BE MAXIMIZED.1.
AIRCRAFT ATTACHMENT POINT, SERVO ATTACHMENT POINT, AND PUSH ROD LENGTH ARE SHOWN
FOR GUIDANCE 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 RECOMMENDED THE GSA28 STOP BRACKET BE
INSTALLED AS SHOWN. WITH THE GSA28 STOP BRACKET INSTALLED, IT IS RECOMMENDED THE SERVO
CRANK ARM STOPS JUST SHORT OF HITTING THE STOP BRACKET AT FULL TRAVEL IN BOTH DIRECTIONS.
BEST CASE SCENARIO WOULD BE TO ACCOMPLISH THIS WITH THE PUSH ROD ATTACHED TO THE
OUTERMOST HOLE IN SERVO. IF ANGULAR SERVO TRAVEL CANNOT BE MAXIMIZED USING THE
OUTERMOST HOLE, USING THE MIDDLE HOLE IS RECOMMENDED PROVIDED THERE IS NO RISK OF
CREATING AN OVER-CENTER CONDITION.
