19. Use a #1 Phillips screwdriver and the screws
provided with the servo to secure it to the servo
mounting blocks. Use side cutters to remove the
unused arm from the servo horn so it does not
interfere with the operation of the servo.
20. Use a pin vise and 5/64-inch (2mm) drill bit to
enlarge the hole on the servo horn that is 11/16-
inch (17.5mm) from the center of the servo horn.
21. Tie the end of the string in the servo opening to
the end of the servo extension.
21. Use the string to pull the servo lead and
extension through the wing and out at the wing
root as shown.
Leave a short 2-inch (52mm) piece of the string
tied to the aileron extension, just in case it
happens to fall into the wing accidentally.
22. Place the servo cover in position in the servo
opening. Use a #1 Phillips screwdriver and two
2.6mm x 8mm sheet metal screws to secure the
cover to the wing.
23. Insert the 4-inch (102mm) pushrod wire into the
hole in the servo horn enlarged in Step 20. Use a
nylon pushrod connector to secure the pushrod to
the servo horn. You may need to use pliers to snap
the connector over the wire.
