2. Drill a 1/16" [1.6mm] hole in the hatch covers through
the mounting blocks approximately 3/8" [9.5mm] deep. Thread
a #2 x 3/8" [9.5mm] fl at head wood screw into each hole
and back it out. Apply a drop of thin CA glue to each hole to
harden the wood. When the CA glue has dried, thread a #2
x 3/8" [9.5mm] fl at head screw into each of the four holes.

3. Cut three arms from a four-armed servo arm for each
aileron servo. Enlarge the outer hole of each remaining arm
with a 5/64" [2mm] drill bit.

4. Attach a 12" [305mm] servo extension to the aileron
servo and secure the connector using tape or heat shrink
tubing (not included). Center the servos with your radio system
and install the servo arms to the servos perpendicular to the
servo cases as shown. Be sure to reinstall the servo arm
screws into the servos.

5. Position the servos against the underside of the aileron
servo hatch covers between the mounting blocks. Drill 1/16"
[1.6mm] holes through the mounting tabs on the servo cases
into the blocks. Thread a servo mounting screw (included with
the servo) into each hole and back it out. Apply a drop of thin
CA to each hole to harden the wood. When the CA has dried,
install the servos onto the hatch covers using the hardware
supplied with the servos.

7. Position the aileron servo hatch covers in place and
drill a 1/16" [1.6mm] hole through the mounting holes and
into the hatch mounting blocks. Thread a #2 x 3/8" [9.5mm]
screw into each hole and back it out. Apply a drop of thin CA
to each hole to harden the wood. Install the hatch covers to the
wings using four #2 x 3/8" [9.5mm] and four #2 fl at washers.
