Great Planes Corsair 40 Kit - GPMA0177 - Manual (Page 22)

D 4. Trial fit the tail gear in the fuse. With the plastic
bushings aligned with the centerline on the back of F-9, trim
the tail gear arm to allow it to rotate through F-9. Roughen
the bushing with 80-grit sandpaper. Thread a swivel
(NYLON20) onto the arm until 1/16" of thread protrudes
from the swivel. To attach the tail gear to F-9, wrap the
lower plastic bushing and F-9 together with a piece of
string. Make sure the bushing is aligned with the centerline
on F-9. Glue the bushing to F-9 with 6-minute epoxy.
D 7. Use medium CA to glue the 1/4" x 24" balsa triangle
sticks (F10) flush to the fuse sides and the bottom of the
formers from F-5 through F-10. Sand the triangle sticks and
fuse sides flush with F-5 through F-10.
D 5. Screw a swivel clevis (NYLON21) 13 turns onto the
end of a 36" wire pushrod (WIRES17). Cut the unthreaded
end to shorten the wire to 23-1/2". Cut six 3/16" bushings
from the plastic inner pushrod tube provided in the kit. Slide
the bushings on the wire pushrod, spacing them about 3"
apart as shown on the plans. If they are too loose, put a drop
of thin CA on the pushrod wire at each bushing to secure
them in place. Locate the bushings on both ends so that
they will not exit or snag on the outer pushrod tubes.
D 8. Sheet the bottom of the fuse with a 1/16" x 3" x 30"
balsa sheet (F18). The sheeting is applied cross-grain.
After the sheeting has been applied, trim and sand the
sheeting flush with the fuse sides.
D 6. Slide the wire pushrod into the outer pushrod tube and
connect the clevis swivel to the swivel. Check that the tail
gear moves smoothly and that the swivel clevis does not
bind on F-9. D 1. Use 30-minute epoxy to glue the 1/8" die-cut ply F-1A
firewall (F04) and two 1/8" die-cut ply F-1B firewalls (F01)
together. Make sure the die-cut punch marks on F-1A are to
the outside.
