Repeat for the other wing.
The flap and aileron T.E. are 1/16”
basswood. Pin the flap and aileron T.E.
in place. Cut 1/16” cap strips and glue
to the T.E. For the aileron, prop up the
tip at R11 and R12. Glue the 1/8” balsa
flap and aileron L.E. in place. Add the
flap and aileron ribs, and cap them with
1/16” balsa. Remove the flap and
aileron from the board and glue the
1/16” plywood control horns in place
with 1/8” ribs on each side.
The flaps are hinged on the bottom with
the covering material, and the ailerons
are hinged along the top.
Fuselage
Prepare the top and bottom stringers as
shown on the plans. A separate drawing
of the right side is included so you can
build both sides at once. Using the
fuselage angle gauge, pin F5, F6, F7 and
F8 over the plans. The formers should
angle forward. Glue the 1/4” square and
1/8”x1/4” balsa stringers to the notches
in each former leaving them long enough
to reach forward of F4. Cut and glue
1/8” square balsa cross bracing as shown
on the plans. The cross bracing should
butt up to each former and be glued to
each stringer it crosses.
