Install the aileron and flap hinges

1. If you have been following the instructions you
should already have the hinge slots located in the
leading edge of the ailerons and flap. Hold the
aileron in place on the wing and mark the location
where the hinge slots need to be cut into the wing
TE. Do this for both aileron locations.
2. If you are making the functional flap, hold the
flap in place and mark the location where the hinge
slots need to be cut into the wing TE.
3. Cut all of the aileron and flap slots into the TE
of the wing.
4. Place all of the control surfaces in place with the
hinges to make sure that everything is properly
positioned. When you are satisfied that everything
fits, remove the control surfaces from the wing. Final
hinge installation will be done after the covering has
been completed.
