NOTE: If you are planning to install a 2-cycle engine
you may use the 1/8" ply fuselage doublers without
any changes. If, however, you will be using a 1.20
4-cycle engine, it will be necessary to cut 3/8" off the
front of the doublers. In the die-cutting process, we
have already started this cut for you, and you may
complete it now. If you will not be cutting off the
front portion of the fuse doubler, apply thick CA glue
to the partial cut which we have made before proceed-
ing to the next step.
2. Find the shaped 3/16" balsa lower front
fuse side and the lower rear fuse side pieces.
Edge glue these pieces to the bottom edge of
the fuse sides in the locations shown on the
plan. Note that the lower rear fuse side pieces
have extra material at the rear portion which
must be sanded off.
3. Glue the die-cut 1/8" ply fuse doublers to
the fuse sides, making one RIGHT and one
LEFT side. Note that the top edge must line
up, and the front of FD must be 3/8" behind
the front edge of the fuse side. A good way to
do this is to carefully align the fuse doublers
and, while holding in position, apply thin CA
glue around the notches and lightening holes,
then around the edges. Make sure you apply
sufficient glue so it flows under the doubler
and produces a strong bond.
4. Insert the following parts into the notches
in the right fuse side: Die-cut 1/8" ply F-2, die-
cut 1/8" ply F-3, 1/4" x 7/8" balsa cross-brace,
and the die-cut 1/8" ply alignment base (AB).
5. Press the left fuse side into place onto the
above parts. Turn the fuse assembly upside
down so the long straight edges of the fuse
sides are resting on a flat surface. Check to
make sure the above parts are all securely in
place and square, then apply thin CA glue to
the joints. Follow up with thick CA glue in any
joints that are not tight fitting.
6. Find the two 1/8" shaped balsa aft deck
base halves and edge glue them together along
the straight edges.
D 7. Carefully position the assembled aft deck
base on the fuse plan top view. Note that the
front edge of the aft deck base must line up
with the dashed line which marks the back of
F-3. Temporarily tape in place.
