7. Cut the covering 1/8" [3mm] inside the opening in
the wing for the aileron servo. Use a trim iron to seal the
covering to the inner edges of the opening.
❏ ❏
8. On the top of the wing, cut the covering away from
the hole at the wing center section. This hole is for the
aileron servo wire to come through, into the fuselage.
❏ ❏
9. On the top and bottom of the wing, cut the covering
away from the hole near the wing trailing edge. This hole is
for the wing bolt.
❏ ❏
10. Remove the string from inside of the aileron servo
bay and tape it to the wing. Do not pull the string out of
the wing!
❏
11. Repeat steps 1-10 for the left wing panel.
❏ ❏
1. Installing the servos in the wing will require the use
of one 12" [305mm] servo extension for each aileron servo.
One Y-harness connector is required and is used to allow
the aileron servos to plug into one slot in your receiver. You
may have a computer radio that allows you to plug the
servos into separate slots and then mix them together
through the radio transmitter. If you choose to mix them with
the radio rather than the Y-harness, refer to the instructions
with your particular brand of radio.
❏ ❏
2. Attach the servo extension to the aileron servo.
Secure the connectors together using a large piece of heat
shrink tubing, tape or other method for securing the
connectors together.
❏ ❏
3. Tie the string from inside the wing to the end of the
servo wire. Pull the servo wire through the wing with the
string. Feed the servo wire out the hole in the top of the wing
center section. Tape the servo wire to the wing to prevent it
from falling back into the wing.
❏ ❏
4. Temporarily position the aileron servo into the servo
bay. Drill a 1/16" [1.6mm] hole through the four mounting
holes of the servo, drilling through the plywood mounting
plate in the wing. Install and remove a servo mounting
screw into each of the four holes. Insert a drop of thin CA
into the holes to harden the wood. After the glue has cured,
install the servo into the servo bay using the hardware that
came with your servo. Center the servo and install a servo
arm as shown.
