Slide four of the hinges into one aileron and center them in the middle
of the hinge slots.
❑
Using a modeling knife, carefully cut a shallow bevel in the aileron
directly above and below each hinge, so that the hinge pivot point can
be recessed into the leading edge.
❑
After the epoxy has set up, test-fit the aileron to the wing panel,
making sure that the leading edge of the aileron is pushed firmly up
against the trailing edge of the wing panel, and that the tip of the aileron
is even with the tip of the wing. There should be no more than a 1/32"
wide hinge gap.
☞
If you can't push the aileron far enough forward to achieve the proper
hinge gap, you will need to cut a shallow bevel in the trailing edge of the
wing for each of the hinges.
❑
When satisfied with the fit, remove the aileron and apply another coat of lightweight oil or petroleum jelly to each hinge pivot
point, then hinge the aileron to the wing, using 5 minute epoxy. Remove any excess epoxy, using a paper towel and rubbing alcohol,
and allow the epoxy to set up before proceeding.
❑
After the epoxy sets up, pivot the aileron up and down several times to free up the hinges. If you notice any excess dried epoxy
on any hinge pivot point, it can be removed by carefully using the tip of your modeling knife to cut it away.
❑
Repeat the previous procedures to hinge the aileron to the other half of the wing, then pull firmly on each aileron to double-check
that the hinges hold securely.

The bevel should be deep enough so that when you push the hinge in further, the pivot point of the hinge will
be flush with the leading edge of the aileron. This will ensure that there will be little to no hinge gap when the aileron is hinged
to the wing.
❑
When satisfied with the fit and alignment, remove the hinges and carefully apply a thin coat of lightweight oil or petroleum jelly to
only the pivot point
of each of the four hinges.

Do not omit this procedure. Applying lightweight oil or petroleum jelly to the pivot point will prevent the hinges
from being glued solid when you install them.
❑
Mix a small quantity of 5 minute epoxy and carefully glue each of the four hinges into only the aileron for now. Make sure that the
hinges' pivot points are straight and flush with the leading edge of the aileron, then remove any excess epoxy, using a paper towel
and rubbing alcohol. Allow the epoxy to set up for about 10 minutes before proceeding.
