8. Install the servo.



 

9. Prepare the linkages and servo arm for outboard 

servo installation.

Order of ball link assembly is bolt through the ball link, 

conical spacer with flat end facing the servo arm, servo arm 

and then nut.



 

10. Attach the linkage to control horn and ball link.



 

11. Screw on the control horn so the distance 

from 

the hinge line

 to the center of the pivot point measures 1 

1/2-inch. 



 

12. Attach the ball link to 1 1/4-inch servo arm hole; in 

case of JR servo arm, this is the second outermost hole.
