 Step 13
Use side cutters to remove the portion of the servo arm that
does not go through the servo cover.
 Step 14
Use a pin drill and 5/64-inch (2mm) drill bit to enlarge the
hole that is 9/16-inch (14mm) from the center of the servo
horn.
 Step 15
Remove the tape that holds the string in the aileron servo
opening. Tie the string to the end of the aileron servo
extension. Use care not to accidentally pull the string out of
the wing.
 Step 16
Remove the flap servo cover. Use the string to pull the
aileron servo lead to the opening for the flap servo.
 Step 17
Use a T-pin to poke through the four holes in the covering in
the aileron servo cover. Position the servo cover in the wing
and use a 1/16-inch (1.5mm) drill bit to drill the four holes
for the servo cover mounting holes. Use caution or you
could accidentally drill through the top of the wing.
 Step 7
Mix a small amount of 30-minute epoxy. Apply the epoxy
to the end of the blocks that were sanded in the previous
step. Position the blocks on the servo cover using the marks
made previously. Use small clamps to hold the blocks tightly
against the servo cover until the epoxy fully cures.
 Step 8
Position the servo between the blocks. Leave a small gap
of 1/32-inch (1mm) between the servo cover and servo to
prevent vibrations from the airframe from being transferred
directly to the servo. Use a pencil to mark the blocks for the
four servo mounting screws.
Hint : Place a 1/32-inch (.5mm) spacer between the
servo and the servo hatch cover before marking the
mounting holes.
 Step 9
Remove the servo. Use a drill and 1/16-inch (1.5mm) drill bit
to drill the four holes for the servo mounting screws.
 Step 10
Apply 2–3 drops of thin CA into each hole to harden the
surrounding wood. This provides a harder surface for the
screws making them more secure when installed.
 Step 11
Use the screws provided with the servo to secure it to the
servo mounting blocks. Use a #1 Phillips screwdriver to
tighten the servo mounting screws.
 Step 12
Secure a 12-inch (305mm) servo extension to the aileron
servo lead. Use string, dental floss or a commercially
available connector to keep the two from unplugging inside
the wing.
