20. Check the gap between the fl ap and aileron. The gaps in
Steps 19 and 20 must be equal before applying CA to the
hinges.
 When the flap is lowered and the aileron is in the
full down position, there may be some interference
between the flap and aileron. In flight, the aileron will
not deflect far enough to interfere with the flap.
21. Apply thin CA to the top of each of the hinges. Make sure to
fully soak the hinges so the CA can wick into the hinge and
bond to the surrounding wood.
 Use thin CA so it wicks into the hinge. A thicker CA
will not wick into the hinge properly. Do not to allow the
CA to run over the covering on the wing and aileron.
22. Allow the CA to cure for 10 to 15 minutes. Gently pull on the
fi xed surface and control surface to make sure the hinges are
glued securely. If not, apply additional CA to secure each of
the hinges.
23. Move the aileron through its range of travel to break in the
hinges.
24. Check both the up and down movement of the hinges before
proceeding.

25. Run your fi nger along the bottom of the aileron to locate the
area for the fl ap control horn. Use a hobby knife and #11
blade to remove the covering, exposing the slot for the control
horn.
26. Locate the two silver aileron control horns. Use medium-grit
sandpaper to remove any paint from the bottom of the control
horn where it fi ts into the aileron.
27. Test fi t the aileron control horn to the aileron. Place tape
around the slot in the aileron for the aileron control horn.
28. Check that the horn is 90-degrees to the surface of the
aileron. If not, lightly trim the hole in the aileron to reposition
the control horn.
29. Remove the aileron control horn from the aileron. Apply epoxy
to the area of the control horns that fi ts into the slots. Use
enough epoxy so the control horns will be fully bonded to the
fi xed surfaces.
