2. Use epoxy to glue in the two nylon wing dowels.

3. Cut eight 3/4" x 1" [19 x 25mm] hinges from the 2"
x 9" [50 x 230mm] CA hinge strip. Snip the corners off so
they go in easier.
❏ ❏
4. Test fit the hinges in the hinge slots of the aileron,
flap and the wing. If you have difficulty inserting the hinges,
insert a #11 blade into the slot and carefully move it back
and forth to slightly widen the slot.
❏ ❏
5. Test fit the aileron and flap to the wing with the
hinges. Use a fine-point ballpoint pen to mark the aileron,
flap and wing at the middle of each hinge. Note: Align the
outer tip of the aileron with the outer tip of the wing. Leave
a 1/8" [3mm] gap between the flap and the aileron.
❏ ❏
6. Separate the aileron and flap from the wing and
take out all the hinges.
❏ ❏
7. Drill a 3/32" [2.4mm] hole, 1/2" [13mm] deep at the
marks you made in the center of each hinge slot. This space
will allow the CA to “wick” in. Follow with a #11 blade to
clean out the slots. Hint: If available, use a high-speed
rotary tool to drill the holes.
❏ ❏
8. Cut a small strip of covering from both sides of
each hinge slot. If this is not done the covering may interfere
with the penetration of the CA into the slot and may also
interfere with the free movement of the aileron.
❏ ❏
9. Stick a pin through the center of each hinge. Fit the
aileron and flap to the wing with the hinges. The pin will keep
the hinge centered. Remove the pins from the hinges. Adjust
the aileron and flaps so there is a small gap–just enough to
see light through or to slip a piece of paper through.
