R7. Glue the canopy fairing supports to the fuse
under the aft edge of the canopy.
❏
R8. Bevel the inside edges of the canopy fairings
as shown on the plan. With the canopy in position,
test fit, then glue the canopy fairings to the fuse. Use
balsa filler to blend the fairings to the fuse. Sand
when dry. The dashed lines in the photo indicate the
edges of the fairings under the balsa filler.
The fuse and cowl can’t be completed until the wing
and the belly pan are built, so clean off your
workbench, take a break, then build the wing!
BUILD THE WING
Preparation
❏
1. Cut the right wing panel plan from the rest of the plan
and lay it on your flat building board. Cover the plan with
Great Planes Plan Protector or wax paper.
❏
2. Make two spar doublers by cutting a 1/4" x 3/8"
x 42" basswood stick into two 21" long pieces. Bevel one
end of both spar doublers as shown on the plan. Make
two more spar doublers the same way (the spar
doublers are pointed out in the following photo).
❏
3. Make four main spars by gluing each spar
doubler to a 1/4" x 3/8" x 42" basswood stick.
❏
4. Position, but do not glue a laser-cut 1/8"
plywood wing rib doubler 5B over a die-cut 1/8"
plywood wing rib 5. Cut away the balsa portion of
the rib that is not covered by the doubler. Repeat for
the other rib 5.
❏
5. Refer to the wing panel plan for the wing you
are building, then glue the laser-cut 1/8" plywood rib
doublers 5A and 5B to both sides of the die-cut 3/32"
balsa rib, making certain you glue the doublers to the
correct sides of the rib.
❏
6. The same as you did in the previous step, refer
to the wing plan for the wing you are building, then
glue the laser-cut 1/8" plywood rib doublers 6A and
6B to both sides of the die-cut 3/32" balsa rib 6,
making certain you glue the doublers to the correct
sides of the rib.
❏
7. Glue the die-cut 3/32" balsa aileron root rib 7B
to rib 7A. Note the two layers of wax paper between
the two ribs aft of the notch. Glue the flap root rib
2D to the side of rib 2B the same way.
