13. Make the tip reinforcement for rib W6 where shown
on the plan from leftover 1/8" plywood, then glue it into
position.
❏ ❏
14. Glue together both die-cut 3/32" balsa wing tip
parts W8 and W9 to make a wing tip. Sand a bevel to the
bottom edge of the wing tip where it joins the wing. Test fit
the wing tip to the wing, make adjustments to the wing tip
where necessary, and then glue it into position.
❏ ❏
15. Cut the outer trailing edge from a 1/4" x 3/4" x 30"
balsa stick and glue it into position to ribs W4 through W6.
Glue a die-cut 1/8" balsa gusset to the outer TE and ribs W4
and W6.
❏ ❏
16. Cut the inner trailing edge from the 3/8" x 1-1/4"
x 24" balsa stick and glue it into position to ribs W2, W3 and
W4 (if you’re on the left wing panel, cut the inner TE from the
remainder of the piece you used for the right panel). Glue
the two gussets where shown on the plan.
❏ ❏
17. Glue rib W2-A into position using the dihedral gauge
to set it at the correct angle and a straightedge to align it
with rib W2.
❏ ❏
18. Use the remainder of the 1/16" x 3/4" balsa stick
you used for the center-section sub leading edge as the sub
leading edge for the outer panel (if you’re building the left
wing panel, use a 1/16" x 3/4" x 30" balsa stick for the sub
LE). Trim the end of the sub LE to match the angle of the
wing tip, then glue the sub LE into position.
❏ ❏
19. Cut the top main spar and the top aft spar at the
wing tip. Use a bar sander with 80-grit sandpaper to sand
the sub LE and the wing tip even with the ribs.
❏ ❏
20. Cut two 1-3/8" shear webs from the 3/32" x 4" x
30" balsa sheet and glue them to the front of the main spars
between ribs 3 & 4 and 4 & 5 as shown on the plan. Save
the rest of the sheeting for the top of the wing.
❏ ❏
21. Remove the wing from the building board. The same
as you did for the trailing edge block on the center-section,
shape the inner trailing edge and the outer trailing edge of
the outer panel to match the shape of the top of the wing.
Trim the bottom spars even with the wing tip. Sand the
bottom LE sheeting even with the sub LE.
❏ ❏
22. Use a bar sander with 80-grit sandpaper to sand the
root end of the wing panel true and even. Use a razor saw
to cut along the lines you marked on ribs W2-A and W2,
making a slot to accommodate the 1/16" ply joiners.
❏
23. Take the right wing panel plan off your building board.
Place the left wing panel plan over your building board, then
return to step 4 and follow the instructions to build the left
wing panel. Be certain to place the left wing panel plan over
your building board, so you don’t build another right wing.
