ASSEMBLE THE WING

INSTALL THE AILERONS

Do the right wing first so your work matches the
photos the first time through.
1. Install a hinge into each of the four hinge
slots in the aileron. Be sure the slit in the hinge is
perpendicular to the leading edge of the aileron.
2. Apply six drops of thin CA to the top and
bottom of each hinge waiting a few seconds
between drops to allow the CA to soak in. Do not
use CA accelerator. After the CA has fully hardened,
test the hinges by pulling on the aileron.
3. Locate the opening for the servo on the bottom
of the wing. Cut the covering from the opening.
4. On the top of the wing locate the 1/2"
[13mm] hole and cut the covering away.
5. Repeat steps 1 - 4 for the left wing.

INSTALL THE AILERON SERVOS AND PUSHRODS

1. Installing the servos in the wing will require
the use of one 6" [152mm] servo extension for each
aileron. 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 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. Attach the servo extension
to the aileron servo. Secure the connectors together
using a large piece of heat shrink tubing or tape.
2. Located in the wing in the servo compartment,
a string is taped to the wing skin. Tie the string 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.
