2.
Puncture the covering so the control horn backing plate
can be accessed by the screws.
3.
Use a hobby knife to separate the control horn backplate
from the control horn.
4.
Insert the three M2 x 25 machine screws into the holes
of the control horn, then into the holes in the aileron.
Make sure the control horn is installed on the bottom of
the aileron.
5.
Slide the control horn backplate on the screws. Apply
a small amount of canopy glue on the screws using a
toothpick, then thread the M2 nuts on the screws. Use
a #1 Phillips screwdriver and 4mm nut driver to tighten

Use side cutters to trim the screws.
7.
Use a fi le to lightly fi le any sharp points from the screws
after they have been trimmed. Use care not to contact
the control surface with the fi le. Prepare and install
the fl ap control horns at this time following the same
procedure as the aileron control horns.
8.
Use a pin vise and 1/16-inch (1.5mm) drill bit to drill
a hole in the center of each hinge slot to allow the CA
to wick into the hinge. Drill holes in both the wing and
control surfaces at this time. The ailerons and fl aps can
both be prepared during this step.
9.
Remove the ailerons from the wing panel. Place a T-pin
in the center of each hinge.
10.
Slide the hinges into position with the T-pin resting
against the edge of the control surface.
