sufficient glue so it flows under the doubler to produce
a strong bond
D 11 From the 3/8" x 30" balsa triangle, cut pieces to
fit between the tail wedge and the rear of F-4, along
the bottom inside of both fuse sides. Glue in place.
D 8. Find the 1-1/4" x 3" tapered balsa tail wedge.
Holding the tail wedge in place on the right fuse side
(aligned with the aft edge of the fuse side) draw a line
on the fuse side at the front edge of the tail wedge.
Now glue the tail wedge to the left fuse side and trim
the ends of the tail wedge flush with the top and
bottom edges of the fuse side.
D 9. Carefully position the die-cut 1/8" ply aft fuse
doublers on the fuse sides The doublers must line
up with the top edge of the fuse sides and the front
edge of the tail wedge Glue the doublers in place.
NOTE: The aft 2" of the top edge of the doubler is
1/8" below the top edge of the fuse,
D 12 Sand the aft ends of the balsa triangle to a
taper, which will permit the fuse sides to be pulled
together at the aft end NOTE: The taper shown in
the photo is approximate and may have to be modified
during assembly.
D 13. From the "ENGINE APPLICATION TABLE"
on the fuse plan, determine which firewall (A, B, or C)
is right for your engine This will govern which firewall
spacers you will use. For instance, if your engine is
an OS 120 Surpass, the "B" firewall applies, and you
will install the "BL" and "BR" firewall spacers If your
engine is not listed in the table, you'll have to compare
the overall length of your engine/mount with the plans
to determine which firewall location is appropriate.
(See step 14 before gluing in the spacers).
IMPORTANT: The purpose of the firewall spacers
is to provide 2-degrees of right engine thrust.
Study the next step carefully and trial fit the parts
before proceeding. The smaller of the two firewall
spacers always goes on the right fuse side.
D 10. The bottom edge of the fuse sides should be
exactly 3/8" below the bottom edge of the fuse
doublers, from F-4 to the aft end, however, there may
be a little extra To insure accuracy, measure and
make marks 3/8" below the doublers near F-4 and
near the aft end, then connect these marks with a
straight line In the next step, install the bottom edge
of the 3/8" triangles along this line.
D 14 Securely glue the appropriate firewall spacers
to the fuse sides and to the front edge of the fuse side
doublers using 5-minute epoxy.
IMPORTANT: For the "C" firewall location, glue
spacer "CL" to the left side and "CR" to the right side.
