Install The Pushrod Tubes; Mount The Stabilizer To The Fuselage - GREAT PLANES Spitfire 40 Instruction Manual

❏
16. Select the two 5/8" x 1-3/8" x 5" balsa fillet blocks and
the two 1/4" x 1-3/8" x 5" balsa false stab and fin.
❏
17. Tack glue the false stab flat onto the aft fuse top and TD4.
Tack glue the false fin vertically onto the false stab, centered on
TD4. Note: The false stab is 1-3/8" across the fuse, 1/4" tall and 5"
long; the false fin is 1/4" across the fuse, 5" long and 1-3/8" tall.
❏
18. Tack glue the fillet blocks to TD4 and the false stab and fin.
❏
19. Using a razor plane and progressively finer grades of
sandpaper, shape the fillet blocks until they blend into and follow
the contour of the fuselage.
❏
20. Cut the fillet blocks and false stab/fin off the aircraft.
Gently remove the false stab and false fin from the fillet blocks.
Set the fillet blocks aside.

Install the Pushrod Tubes

❏
1. Select the two 36" grey plastic outer pushrod tubes. Sand the
outside of the tubes with coarse sandpaper so the glue will stick.
❏
2. Insert the rudder pushrod tube through the slot in the left
aft fuse side, through the center hole in F4, and through the
right hole in F3. Approximately 1/8" of the tube should protrude
past the rear edge of the slot in the fuselage side.
❏
3. Insert the elevator pushrod tube through the hole in the
right aft fuse side, through the right upper hole in F4, and through
the center hole in F3. Approximately 1/8" of the tube should
protrude past the rear edge of the slot in the fuselage side.
❏
4. Glue the pushrod tubes to F3 and F4 with medium CA.
❏
5. Use a mixture of 30-minute epoxy and microballoons to
secure the tubes to the slots at the aft end of the fuselage.
Completely fill the slots with the microballoons and epoxy. Allow
the epoxy to cure completely.
❏
6. After the epoxy has cured, use a bar sander and sandpaper
to sand the outer pushrod tubes and epoxy filler flush with the
fuselage sides.
❏
7. Cut the excess pushrod tube inside the radio compartment
1/4" aft of the servo opening.
❏
8. Using leftover 1/4" x 1/4" balsa stick, cut, fit and glue a fuse
end cap between the fuse top, fuse bottom, and fuse sides at
the trailing edge of the fuse.

Mount the Stabilizer to the Fuselage

❏
1. If you have not already done so, make sure the stab and
fin are final sanded to a smooth finish, as it will be a little more
difficult to do so after they are glued to the fuselage.
