❍
(8) Temporarily position a servo and cut 3/32" balsa sheeting
to fit the two aileron servo areas and the center section. Leftover
sheeting can be used along with a 3/32" x 3" x 36" sheet supplied
for this purpose. Use the plan to determine the hatch location.
❍
(9) Cut, fit and glue the 1/4" square, hard balsa hatch mount
rails between the ribs as shown on the plan. Trim the 1/16" x 3-
1/4" x 5-1/4" plywood hatch cover to fit as shown. See the plan
for the correct location of the six #2 x 3/8" flat head hatch
screws. Drill and countersink the six screw holes.
Drill 1/16" pilot holes into the hatch mount rails. Test fit the
hatch to the wing using all six screws. Remove the hatch when
you are satisfied with the fit. Apply a couple of drops of thin CA
to each screw hole in the mounting rails to harden the balsa.

❍
(10) Trim and glue the 3/32" x 1/4" balsa cap strips to the
wing ribs.
❍
(11) Remove the wing from the building board and turn it over.
The trailing edge fixture is no longer needed to support the TE of
the wing. Sand the sub-leading edge so that it’s flush with the tops
of all ribs as shown. Glue the second 3/32" x 3" x 44" leading
edge sheet to the ribs, beveled sub-leading edge and spar.
