radio and center the servo. Test fit the servo in the servo bay.

Adjust the servo arm until one of the arms is at a 90° angle to

tack glue the servo in place with a drop of medium CA.

a nylon FasLink and trim off the excess pushrod, leaving

approximately 1/16" [1.6mm] past the FasLink. Remove the
