remove any arms that do not protrude to the outside of the
cover.
41. When attaching the linkage to the aileron servo arm, use the
hole in the arm that is 5/8-inch (16mm) from the center of

the pushrod at the mark made in the previous step. Use side
cutters to cut the end of the pushrod so the inside dimension
