14. Tape the flap to the wing. Sand the TE of
the wing to match the flap TE angle. Leftover balsa
sheet can be used to fill any gaps between the
wing sheet and former 8-C.
❏
15. Go back to step 1 and repeat the process to
build the other flap.
BUILD THE FUSELAGE
BUILD THE FUSE SIDES
❏
1. Test fit the die-cut 3/16" balsa upper
forward fuse side, upper aft fuse side, middle
forward fuse side, middle aft fuse side, lower
forward fuse side and radiator side together.
These should be aligned over the fuselage side
view on the plan or by placing a long straightedge
along the top edge of the upper parts. Adjust any
joints that do not fit well.
❏
2. Place wax paper or Plan Protector over your
work surface. Reassemble the parts over the plan
and check their alignment. For a straight fuselage, it
is important to have the fuse sides straight and
identical. Use thin and medium CA to glue the parts
together. Use a quick wipe with a paper towel to
remove excess glue, as this will make sanding
easier. Keep in mind that you are making a left and
a right fuselage side.
❏
3. Inspect the two fuselage sides. Choose the
right and left sides so the best surfaces will face
outward. Mark the inside of the appropriate part RI
and LI (for right inside and left inside). Sand both
sides of the fuselage sides to smooth out the joints.
❏
4. Glue a die-cut 1/8" plywood aft fuse doubler
to the inside of each fuselage side. Be sure to
make a left and a right side. Align the stab
saddle and the top edge of the doubler with the
fuse side when gluing.
❏
5. On one of the die-cut 1/8" plywood fuse
doublers draw a line 5/32" back from the forward
edge. Trim the fuselage doubler to this line. Mark
this doubler “R” (right) and the other doubler “L”
(left). This will set the right thrust in the firewall.
❏
6. Line up the fuse doublers using the notch at
the back of the wing saddle as the primary
reference. Be sure to put the right fuse doubler on
the inside of the right fuse side. Glue both doublers
in place.
❏
7. Glue the die-cut 1/8" balsa forward fuse
doublers in place. They should touch the plywood
fuse doublers.
❏
8. Cut two 11-5/8" long doubler sticks from the
1/8" x 1/2" x 24" balsa stick. Glue the doubler
sticks along the top edge of each fuse side
beginning at the notch in the aft fuse doubler.
