Prepare The Polyhedral Braces - Top Flite CESSNA 182 SKYLANE Instruction Book

support the flap and aileron servo hatches.
Install the rails even if you don't plan to add
flaps, as they add a little extra strength and fill in
the notches.
15. Glue the 1/8" die-cut Gusset G-3 to the
Aft Outer Spar and W-7, as shown on the plans.
16. Hold the 36" shaped balsa LE up to the
wing and mark it at W-7. Cut three quarters of
the way through the LE (from the flat side) with a
razor saw to allow it to flex at W-7. Center the
LE vertically on the ribs, then tack glue it in
position at W-4, W-7 and W-14. Sight down the
LE from both ends to check that all of the ribs
are centered and that the frame isn't curved or
twisted. Once again, be sure that all the jig tabs
are firmly on the building board, then
permanently glue the LE to all of the ribs.
FLAP SPAR
17. Cut the tapered 30" balsa Flap Spar to
fit from W-4 to W-7 then glue it into the "V"
notches just behind the aft Inner Spar.
18. Center a 1/2" x 15" tapered balsa TE on
the aft edge of W-4 and the last W-6, then glue it
in position to only W-4 and W-6. Lay a
straightedge across the aft end of the ribs to
check that all ribs are aligned and level and that
the TE is straight. When everything looks good,
glue all the remaining ribs to the TE, centering
each rib as you proceed.
19. Glue the die-cut 1/8" balsa gussets G1
and G2 in position, as shown on the plans.
20. Trim the excess material from the
Spars, LE, TE, etc., and sand all ends flush.
Reinforce all joints that still need extra glue by
adding medium CA.
21. Refer to the plan for the location of the
single and double 1/16" x 2-3/4" x 1-1/2" balsa
Shear Webs. Glue the Shear Webs in position
with thick CA (Not between W-4 and W-5).
22. Locate the 1/2" x 1/2" x 6" balsa stick.
Cut six 1" lengths to use as Aileron Hinge
Blocks. Fit and glue 3 blocks where shown on
the plans. Save the other 3 for use on the
second wing panel.

Well, that about wraps up the framing for half of
the wing. Take a short break to admire your
handiwork, have a cup of coffee, clean the CA off
your fingers, and kiss your spouse good night.
When you're fully revived, clean the sawdust off
your bench, swap the plan sheets, and get busy
building the other half. You can rest later.

Prepare the polyhedral braces

1. Position the three 1/8" ply parts of the
Polyhedral Braces over the sketch on the
plans. Look carefully at each piece and you will
notice that they form a slight "V" shape, with one
end longer than the other. After you align each
piece over the drawing, mark an index line on
each part as shown, then extend it around to
both edges.
2. Without gluing, stack the three pieces
together and compare the assembly with the
photo and the plans. Repeat this process with
the second set of braces, but this time flip the
pieces end-for-end when you stack them.
