Step 3. Allow the epoxy to fully cure for at least 6 hours. When

cured, work each hinge throughout its full motion several times

using your hands. This will break free any epoxy that may have

found its way into the hinge joint. Move the hinge throughout its

full travel until no resistance is felt. This may take as many as

40 or 50 times.

Step 4. Mix 1 ounce of 30-minute epoxy. Using a syringe or

toothpick, place a sufficient amount of epoxy in each of the hinge

pockets in one aileron half.

Step 5. Carefully install the aileron on the wing, making sure

the hinges are inserted in their respective hinge pockets. Press

the aileron and wing together such that less than a

/64" hinge

line gap exists between the aileron and wing. The bevels should

virtually touch. Using a paper towel and rubbing alcohol, wipe

away any visible epoxy around the hinges.

Step 6. Double-check the hinge gap and allow the epoxy to

fully cure for at least 6 hours. Now is a good time to epoxy the

hinges on the other aileron half using the same techniques.

Step 7. When fully cured, move each control surface

throughout its travel range several times to break away any epoxy

in the hinge. Be sure to deflect the surface fully.
