wood!). Apply thick CA glue to the edges of the formers
and the stringers, then immediately bend the sheeting
around the formers and onto the stringers. HINT: This
requires about 5 sets of "hands," so use several long
pieces of masking tape to pull the sheeting together, then,
working a small section at a time, add CA and press the
sheeting to the stringers.
9. Trim and sand the sheeting flush with the front
of F-3A and the rear of F-6A.
ASSEMBLE THE NOSE SECTION
Cut off one end of each stick at an angle to fit the front
edge of the backrest (F-3A).
sides and to F-3A. The outside edge of the cockpit sides
should be flush with the outside edge of the fuse sides.
1. Find the 1/4" x 1/4" x 7-3/4" balsa cockpit sides.
2. Glue the cockpit sides to the top edge of the fuse
10. Using a long T-bar or sanding block with 80-grit
sandpaper, sand the sheeting and stringers flush with the
top edges of the formers.
3. Sand off the front of the cockpit sides on the
same angle as the front 1-1/2 inches of the fuselage.
11. Glue the 3/8" x 2" x 24" balsa turtle deck top
block to the tops of the formers, stringers and sheeting,
then trim the ends of the top block flush with F-3A and
F-6A.
HINT: In the next step it will be helpful in keeping
the top block symmetrical if you first mark a
centerline on the top of the top block from front to
back.
12. Carve and sand the top block to blend smoothly
engine to the mount. Remove the nose gear.
5. From a scrap of 1/32" ply, cut four small pieces
and tack glue them to the 1/16" ply spinner ring as
shown, using a very small amount of thick CA (these will
be removed later). IMPORTANT NOTE: If you have
chosen to use shock absorbing rubber "Lord" mounts,
then you must provide more space between the spinner
ring and the spinner backplate to allow for engine move-
ment. A space of approximately 1/8" is probably suffi-
cient.
4. Attach the engine mount to F-l, and attach the
with the sheeting (see the cross-section on the plan).
HINT: Use a razor plane and a sanding block with 50-
grit sandpaper for rough shaping the top block.

6. Now center your 2-1/4" diameter spinner
backplate over the spinner ring, and tack glue it to the
1/32" ply spacers.
