insides of the joiner pockets in each wing panel with epoxy.
Coat one half of the wing joiner and slide it into one of the
panels. Coat the root ribs of both panels and the other end
of the joiner. Join the panels together. Wipe away excess
epoxy with denatured alcohol. Masking tape can be used
to hold the panels together while the epoxy cures. We also
recommend using small clamps to align the trailing edge and
to squeeze the LE tabs together as shown. Allow the epoxy
to cure undisturbed.

4. Center the plywood aileron servo tray over the opening
on top of the wing. Trace around the inner and outer edges of
the tray onto the wing using a felt-tip pen. Use a sharp hobby
knife to cut the balsa and covering from the inner lines you
drew, and just the covering from where the tray will be glued.
Take care to cut just through the covering and not into the
wood along the outer lines you drew. Wipe away the lines
with denatured alcohol and glue the tray in place.

5. Fit the aileron servo into the tray with the servo spline
towards the LE of the wing. Drill 1/16" [1.6mm] holes through
the mounting tabs on the servo into the tray. Thread a servo
mounting screw (included with the servo) into each hole and
then back it out. Apply a drop of thin CA to each hole to
harden the surrounding wood. Install the servo using the
hardware included with the servo.
❏
6. Use your radio system to center the servo. Cut two
arms from a four-arm servo arm. Use a 5/64" [2mm] drill bit
to enlarge the holes on each remaining arm that are closest
to 7/16" [11mm] from the center of the servo spline. Install
the servo arm perpendicular to the servo case being sure to
reinstall the servo arm screw.

7. Thread a nylon torque rod horn onto each aileron torque
rod as shown.
