41. Mark the trailing edge of the wing where the aileron
ends between W2 and W3. Mark one piece of aileron stock
1/2" longer than that distance. Cut the aileron stock at that
mark and glue it to the trailing edge of the wing as shown
above. Also, sand the stock flush that extends past the
root rib.
❏ ❏
42. Place the aileron at the trailing edge of the wing
against the piece you just glued. Draw a line at the tip rib on
the aileron. Cut the aileron stock to length.
❏ ❏
43. Use the same method described on step 14, page
10 to draw a centerline on the wing trailing edge and aileron
leading edge. Mark the location of the CA hinges on the
aileron and wing trailing edge as shown on the plans. Cut
the hinge slots using the same method you used for the
elevators.
❏ ❏
44. Bevel the aileron as shown. Test fit the aileron to
the wing trailing edge with the CA hinges. Sand the sides
and the top or bottom of the aileron as needed to account
for the wing taper.
