Glue the joiner into the wing
❏
11. Mix 1/4oz. (7.5ml) of 30-minute epoxy to glue
the joiner into one wing half. Use a mixing stick or
epoxy brush to apply epoxy to all four sides of the
joiner cavity wall. Insert the joiner into the cavity up
to the centerline marked on the joiner plate. Be sure
you are installing the joiner in the correct orientation
to the wing. Clean the excess epoxy from the wing
root rib. You must be sure all the excess glue is
removed from the wing root or the wings will not fit
together correctly. Allow enough time for the epoxy to
fully cure before proceeding to the next step.
Apply the epoxy to the wing root
❏
12. Mix 1/2oz. (14.5ml) of 30-minute epoxy and
apply to the wing root rib and inside the joiner cavity
of the second wing half.
Join the wing halves
❏
13. Assemble the two wing halves with the tightest
seam possible.
No gaps
should be showing between
the two wing halves. Clean the excess epoxy from the
outside of the wing using a paper towel dampened
with rubbing alcohol.
Tape the wing halves together
❏
14. Hold the wing halves in alignment while the
epoxy is curing. Use several strips of masking tape on
both sides to hold the wing halves tightly together. Let
the glue cure.
Cut the aileron servo hole
❏
15. Remove the masking tape from the wing. With
the wing lying upside down and the leading edge
facing away from you, hold the aileron servo tray onto
the bottom of the wing. The front inside edge of the
tray should be placed so the notch is 1/16" (1.5mm)
behind the wing joiner locator line, drawn earlier, and
centered directly over the wing joint. Using a felt-tip
pen, trace the inside of the tray. Use a hobby knife
with a
new
blade to carefully cut out the aileron servo
hole. Remove enough of the balsa center rib to allow
the servo to be inserted, but
do not cut through the
top side of the wing or into the wing joiner cavity.
