❏ 2. Test join both outer panels to the center section with
the polyhedral braces. Use small clamps to temporarily hold
everything together. Both wing tips under rib W7 should be
3" [76mm] above the workbench. If the distance is not
exactly 3" [76mm] it’s okay, as long as it’s close and both tips
are the same. Hint: Cut a leftover balsa stick to the correct
length and use it as a gauge for both wing tips.
❏ 3. Once satisfied with the fit, separate the panels. Cover
your workbench with a sheet of Plan Protector. Mix up a
batch of 30-minute epoxy, then coat all joining surfaces.
Rejoin the panels with the polyhedral braces and place the
wing on your protected workbench. Position the clamps and
wipe away excess epoxy before it hardens. Do not disturb
the wing until after the epoxy hardens. Hint: If more working
time is required, join one wing panel at a time with separate
batches of epoxy.
❏ 4. Glue in the rest of the 1/32" [.8mm] shear webbing
between the ends of the polyhedral braces and ribs W2.
Skip this section if not building ailerons.
Only the left aileron is shown in the photos, but both ailerons
are built at the same time.
❏ 1. Cut two bottom aileron sheets to the size shown on
the plan from the 1/32" x 3" [.8 x 76mm] balsa sheets
leftover from making the shear webs. Pin the sheets over
their location on the plan.
❏ 2. Glue the laser-cut 1/16" [1.6mm] balsa aileron ribs to the
sheet where indicated on the plan.
❏ 3. Cut the top aileron sheets from a 1/32" x 3" x 15" [.8
x 76 x 380mm] balsa sheet. Note that the top sheets should
be 1/16" [1.6mm] wider than the bottom sheets. Glue the top
aileron sheets to the bottom aileron sheets and the ribs.
❏ 4. Remove the ailerons from the plan. True all edges with
a bar sander and 150-grit sandpaper.
❏ 5. Cut a 1-1/8" [29mm] torque rod tube from both 1/16"
x 12" [1.6 x 305mm] aluminum tubes. This is best done by
rolling the tubing under a #11 blade on the workbench to cut
the tubing without burring the end.
