Glue the longer 20”
carbon flat spar to the
back of the center wing
panel. Make sure it is
centered equally on
the left and right of the
wing. Use wax paper to
keep your fingers clean.
Repeat this process for
the other side.
(In case you don’t get
it: It is being glued to
the trailing edge of the
smaller center wing
panel)
It will require some light
bending. It will bend
very easily as long as
your flat spar is
standing vertically and
not laying flat.
With the Remaining
shorter flat spar repeat
the same process but
on the front leading
edge of the center wing
panel. Again using wax
paper to keep your
fingers clean.
Spraying accelerator
while holding the spar
with the wax paper will
make the end parts that
curve easier to as-
semble.
Use small 1/8” strip of
masking tape to line up
the top cover. This will
help you get the wing
on right with one try
by flipping it over after
you apply glue on the
inside.
Apply glue to sections
in Red. Marking yours
the same way only on
the outer most edges
will help you in later
steps with sanding the
leading and trailing
edges
. (Don’t forget
to apply glue on the
Carbon tube also)
Carefully flip over the
top and make sure it is
lined up. Hold it down
with pressure until the
glue starts holding.
Spray accelerator over
the edges to assist.
Cut and trim the balsa
wood aileron stock to
fit.
Sand the inside edge
lightly if needed to
form a nice clean edge
for the aileron. Use a
Sanding Bar for even
results.
With the wing upside-
down attach the aileron
so that it will lay flat
when right-side up as
shown in the next step.
If your aileron is thicker
than your wing then
sand it down to create
a smooth air flow over
the wing. If it fits nicely
then just leave it as it is.
Again use a sanding
bar.
