❑
Cut out a 1-1/2" square piece of waxed paper.
❑
Slide the waxed paper between the torque rod wire and the
trailing edge of the wing.
☞
The waxed paper will prevent epoxy from gluing the torque
rod to the trailing edge.
❑
When satisfied with the fit, remove the aileron from the wing, but leave the hinges in the aileron.
❑
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 aileron 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.
❑
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.
❑
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.
PRO TIP
STEP 2: HINGING THE ELEVATOR HALVES
❑
Carefully thread one nylon adjustable control horn onto each
threaded elevator torque rod wire. The control horns should
both face the front of the fuselage and they should both be
flush with the top of the torque rod wires, too.
☞
It's much easier to thread the control horns into place now,
rather than waiting until after you've hinged the elevator halves.
