❏ 6. Laminate two of the die-cut 1/8" balsa top
spines, making a 1/4" spine. Laminate the other
two, making a second 1/4" spine. Glue the spines
to the top sheeting, with the forward edges 1-1/4"
from the fuse side and the rear edges against the
fin and the forward edge of bulkhead 7.
❏ 7. Sand the front of the spines to the shape
shown on the plans. Fill in around the dorsal fin
and the spines with leftover 3/8" x 1/2" balsa stick
and filler.
MAKE AND MOUNT
THE WING STRUTS
❏ 1. Drill an 1/8" hole which is 3/4" deep in one end
of each of the four shaped basswood wing struts.
❏ 2. Thread four 6-32 x 1-1/2" studs into the struts
until 3/4" of the stud is protruding from the end of
the strut. Do not glue at this time. Note: You will
permanently secure the studs to the struts after the
model is completely covered and all measurements
and alignments have been checked.
❏ 3. Using the wing plans as a reference, drill four
1/8" holes through the bottom sheeting and through
the four basswood strut blocks.
❏ ❏ 4. Screw one of the nylon strut ends onto one
strut. This is now your front strut.
❏ ❏ 5. Cut the belly pan sheeting behind sub-
former 3 until you can fit the nylon strut end in the
slot. Drill a 1/8" hole for the strut mounting screw.
Mount the front strut to the fuse with a #8 x 3/4"
truss head screw.
