8. Glue the bottom aileron skin to the top
aileron skin with medium or thick CA. Be certain to
use plenty of CA along the TE to ensure a good bond
and to increase the rigidity of the TE.
❏ ❏
9. Use a razor saw to cut the aileron from the
wing. Trim the ribs even with the outer TE spar on the
wing, and the aileron spar. Finally, trim the top of the
mid and outer TE spars even with the top sheeting.
❏ ❏
10. Cut the aileron LE and the outer wing TE
from the 1/4" x 1" x 30" [6.4 x 25.4 x 762mm] balsa stick.
Glue both parts to the aileron and wing respectively.
❏ ❏
11. Shape the aileron LE even with the aileron
and shape the outer TE even with the wing.
❏ ❏
12. Tack glue the aileron to the wing. The
aileron and wing should already match up well, but
sand where necessary for a seamless transition.
❏ ❏
13. The same as the stab and fin tips, make the
wing tip by gluing a die-cut 3/32" [2.4mm] balsa
wing tip core (WTC) between the wing tip top cut
from the 3/4" x 1-1/2" x 18" [19 x 38 x 457mm] balsa
sheet and the wing top bottom cut from the 1/2" x 1-
1/2" x 18" [13 x 38 x 457mm] balsa sheet. Be certain
the 1/2" [12.7mm] sheet is on the bottom.
❏ ❏
14. Glue the wing tip to the end of the wing
panel making certain the front of the core aligns with
the leading edge and that the back of the core aligns
with the TE of the aileron.
❏ ❏
15. Sand the wing tip even with the wing, then
round the corners.
❏ ❏
16. Carefully “break” the aileron free from the wing.
❏
17. Fill the space between the wing tip and the
wing with leftover balsa or balsa filler.
❏ ❏
18. Cut the hinge slots in the aileron and the
wing. Bevel the LE of the aileron for control throw.
Cut four more 3/4" x 1" [19 x 25mm] CA hinges and
test fit the aileron to the wing with the hinges. Be
certain enough control throw can be achieved as
indicated in the
Control throws section on page 63.
