8. Use a razor plane and sanding bar to shape the
aileron ribs and LE to shape.
❏ ❏
9. From the leftover 1/4" x 1/4" balsa stick, cut and glue
an aileron LE doubler behind the aileron LE, between the
ribs that are in line with the aileron servo tray.
❏ ❏
10. Position the die-cut 1/8" plywood aileron horn base
on the aileron LE and LE doubler. Mark the outline of the
base on the LE and doubler.
❏ ❏
11. Mark the location of the hinges on the aileron and wing.
❏ ❏
12. Remove the aileron from the wing and trim the
aileron LE and LE doubler to recess the aileron horn base
flush with the top of the aileron ribs and LE. When satisfied
with the fit, glue the aileron horn base to the LE, LE doubler
and aileron rib.
❏ ❏
13. Draw a centerline on the LE of the aileron and the
TE of the aileron bay. Note: The centerline is not centered
at the tip of the aileron.
❏ ❏
14. Cut the hinge slots in the aileron and the wing. Cut
three 3/4" wide hinges from the supplied hinge strip and trim
the corners. Insert the hinges in the aileron and fit the
aileron to the wing. Do no glue until told to do so.
❏ ❏
15. Remove the aileron from the wing. Mark the “bevel
to” lines on both sides of the aileron, 3/16" from the LE.
Shape the LE of the aileron to a “V” as shown on the plan.
❏ ❏
16. Check the fit of the aileron on the wing. The aileron
should have 3/4" to 1" of throw each way.
❏
17. Return to step 1 of Assemble the Ailerons and build
the second aileron.
