You should now have a
completed wing half that looks like
the picture. Use a straight edge to
trim the balsa TE to meet at each
panel. LIGHTLY sand the sheeting
for covering, but remember it is
very thin, so do not sand through!
18.
The LE balsa needs to be
applied as shown as it adds
tremendous strength to the wing
joints. Epoxy the first panels LE to
the cores. Now sand it to match the
LE angle of the second panel.
19.
Epoxy the second LE on the
middle panel, overlapping the first
panels LE. Now sand the LE to
match the angle of the outer panel.
20.
Finally epoxy the outer panels
LE to overlap the middle. Sand all
of the LE's to the airfoils contour.
Use discretion to the final LE
shape. A sharp LE will yield higher
speeds and better penetration, but
will stall abruptly. A more blunt,
round LE will stall gently, but not be
as fast.
21.
Glue the balsa block wing tips
in place then sand to match the
shape of the wing.
22.
Cut Ailerons out of the TE of
the outer 2 panels. The Ailerons
should be 1.5" at the root and taper
to .75" at the tip.
23.
Remove 1/8" of material from
the face of the aileron and TE and
then face with 1/8" balsa for
hinging.
24.
Use a sharpened ¼" brass
tube to cut a servo lead hole from
the root to the tip of the inner
panel. It should be located in the
center, at the thickest part of the
wing. Do this to both panels.
25.
Use a sharp x-acto blade to
cut a servo bay at the end of the
INNER wing panel. The bay should
be placed over the servo tube hole
you just cut. The bay should be
sized to hold the servo flush and
tight against the foam.
26.
Cut a notch on the BOTTOM
of the wing at the center section for
access to the servo wires after
wing joining.
27.
Place the two wing alignment
blocks to prop the wing into joining
