3. Locate one nylon servo arm, and using wire
cutters, remove all but one of the arms. Using a
2mm drill bit, enlarge the third hole out from the
center of the arm to accommodate the aileron
pushrod wire.
4. Plug the aileron servo into the receiver and
center the servo. Install the servo arm onto the
servo. The servo arm should be perpendicular
to the servo and point toward the middle of the
wing.
5. Center the aileron and hold it in place using a
couple of pieces of masking tape.
6. With the aileron and aileron servo centered,
carefully place a mark on the aileron pushrod
wire where it crosses the hole in the servo arm.
7. Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess
wire, leaving about 4mm beyond the bend.
8. Insert the 90 degree bend down through the
hole in the servo arm. Install one nylon snap
keeper over the wire to secure it to the arm.
Install the servo arm retaining screw and
remove the masking tape from the aileron.
