may cut out the fuselage top and side views and work
with them separately.

D (1) Each Firewall Spacers (see text)
D 3 Carefully position the die-cut 3/16" balsa lower
front fuse side so the vertical rear edge lines up with
the front of the wing saddle opening on the plan (the
rear edge of F-2A) You may have to lightly sand the
top edge of the die-cut 3/16" balsa for a good fit
against the bottom edge of the fuse side Edge glue
the lower front fuse side to the fuse side NOTE: Use
waxed paper under the balsa to avoid gluing to the
plan.
D 1. Trial fit the 3/16" balsa aft fuse side against the
aft edge of the long 3/16" balsa fuse side Lay a
straightedge along the top edge of these parts to
insure straightness Sand the mating edges as
necessary for a good fit Glue the aft fuse side to the
fuse side, using thick CA, epoxy or aliphatic resin glue.
Block sand the joint smooth on both sides.
D 4 Carefully position the die-cut 3/16" balsa lower
rear fuse side so the vertical front edge lines up with
the rear of the wing saddle opening on the plan (the
front edge of F-4) Edge glue the lower rear fuse side
to the fuse side.
D 5. Trim and sand off the die-cut "bumps" from the
front and rear portion of the lower rear fuse side,
blending with the upper fuse side.
D 6 Block sand the fuse side smooth on both sides
using a T-bar and 100-grit sandpaper Then repeat
the above steps to make the other fuse side.
CAUTION . . . Do not make two Left sides!
D 2 Lay the fuse side in place on the fuselage plan
side view Carefully align the long top edge of the
fuse side with the corresponding line on the plan, and
position it so the front edge lines up with the
alignment arrows (approx 3/32" forward of the front
edge of F-1) on the plan Tape or pin the fuse side so
it can't move NOTE: The fuse side may be a little
longer at the rear than indicated by the plan. This is
as it should be
D 7. Carefully position the large die-cut 1/8" ply
fuselage doublers on the fuse sides, making a RIGHT
and a LEFT side It is important that the fuse doubler
and fuse side line up along the top edge and the front
of the wing opening While holding in position, apply
thin CA glue around all the notches and lightening
holes, then around the edges. Make sure you apply
