❑
Push the aileron and its hinges into the hinge slots in the trailing edge of the wing, making sure that the torque rod wire is firmly
seated within the precut slot in the aileron.
☞
The aileron should be pushed firmly up against the trailing edge, so that there is a minimal hinge gap (no more than 1/32" wide),
and the ends of the aileron should not rub against the edges of the wing.

You may need to cut the slot in the aileron for the torque rod wire deeper, so that the aileron can be pushed
forward enough to result in no more than a 1/32" wide hinge gap.
❑
When satisfied with the fit, remove the aileron from the wing, but leave the hinges centered in the aileron.
❑
Cut out a 1-1/8 long x 1" wide piece of waxed paper.
❑
Slide the waxed paper between the torque rod wire and the trailing
edge of the wing.

❑
Remove the T-pins from the hinges, and while holding the aileron
tight against the wing, pivot the aileron down about 45º and apply 5-6
drops of thin C/A to the exposed area of each hinge. Turn the wing
over and repeat for the other side of the hinges.
☞
Remove any C/A that may run down the hinge line, using C/A
Debonder.
PRO TIP
STEP 2: HINGING THE ELEVATOR HALVES
❑
Push two T-Pins through the center of two C/A style elevator hinges.
❑
Working with one elevator half for now, slide one hinge into each hinge slot in the elevator half, making sure that you push
each hinge in up to the T-Pins. Don't glue the hinges into place yet, though.

The waxed paper will prevent epoxy from gluing the torque rod wire to the trailing edge of the wing.
❑
Using 220 grit sandpaper, lightly sand the end of the torque rod wire to roughen the surface, then mix a small quantity of 5 minute
epoxy and apply a thin layer to the end of the torque rod wire and into the predrilled hole and the precut slot in the leading edge of
the aileron.
❑
Push the aileron and its hinges into the hinge slots in the trailing edge of the wing and align the aileron as done previously.
❑
Allow the C/A and epoxy to dry for about 15 minutes, then pivot the aileron up and down several times to free up the hinges.
After the C/A and epoxy have fully cured, gently grasp the aileron and wing and pull on the aileron like you are
trying to pull out the hinges. The hinges should hold securely. If one or more hinges feels loose, apply more C/A to the hinge(s)
and allow it to completely cure.
❑
Repeat the previous procedures to hinge the second aileron to the wing, making sure to check the integrity of the hinges
after the C/A and epoxy fully cure.
