3. Inspect the hinges and make sure that each hinge is seated properly. Adjust any
hinge holes that are impeding movement. Remove all of the hinges from the wing and
aileron. Mix a generous batch of 30 minute epoxy. Use a zip tie or an old pushrod to
thoroughly coat and fill the hinge holes in the wing with epoxy. Coat one side of each
hinge with epoxy and insert it into the wing taking great care to make sure it is
centered properly. Wipe away any excess glue with an alcohol soaked rag or paper
towel. Once all hinges are installed in the wing set it aside to dry.
4. Once dry use the same procedure to fill the hinge holes in the aileron with epoxy.
Coat the protruding hinges with epoxy then slide the aileron into position. Make sure
the aileron is seated properly with minimal gap between the wing and aileron and wipe
away any excess glue with an alcohol soaked rag. Pay careful attention to wipe any
excess glue from the hinge knuckle. Set the assembly aside to dry. Once dry the
aileron movement may feel a bit stiff. A drop of Acetone placed on the knuckle of each
hinge will help to free the aileron. Then apply a drop of Teflon or silicon lubricant to
each hinge and work it into the joint by moving the aileron back and forth multiple
times. Wipe away any excess lubricant with an alcohol soaked rag. Now is a good time
to seal the hinge line gap with Blenderm tape or Oracover (Ultracote) if you desire to
do so.
5. Secure a 6 inch servo extension to the aileron servo lead and install your aileron
servo as shown with the output shaft oriented toward the leading edge of the wing.
