9. Test fit the elevator to the stab with the
hinges. Shift the elevator over to create a 1/32" gap
between the elevator tip and the end of the stab at
S-6. Sand the elevator tip to match the stab tip.
❏ ❏
10. Shape the LE of the elevator to a “V” for
control throw. Make certain you can achieve 5/8" of
both up and down control throw as described in the
Control Throws section on page 58. Increase the
angle of the bevel if necessary.
❏
11. Repeat steps 3 through 10 to finish the
other elevator.
❏
12. With the elevators temporarily connected to
the stab with the hinges, center the elevator joiner
wire on the elevators where shown on the plan. Use
a ballpoint pen to mark the location of the joiner
wires on the elevator root blocks.
❏
13. Drill 1/8" holes and cut grooves in both
elevators to accommodate the joiner wire. Hint: Use
a 1/8" brass tube sharpened on one end to cut the
grooves in the LE.
❏
14. Test fit the elevators to the stab with the joiner
wire. Make certain both elevators are parallel. If
necessary, bend one of the “arms” of the joiner wire
to align the elevators with each other.
Note: If you
found it necessary to bend the wire, it must be
inserted into the elevators the same way when it’s
time to glue it in.
Build the fin
❏
1. Cut the fin plan from the side view of the fuse
plan along the dashed lines. Place the fin plan over
your building board. The same as the stab, if you
work carefully there is no need to protect the plan
from glue.
Refer to this photo for the following two steps.
❏
2. Just the same as the stab, hold the die-cut 3/32"
balsa fin ribs V-1 through V-5 over the plan with rib
jig sticks cut from two 1/4" x 1/4" x 24" balsa sticks.
Note that the widest part of each rib is the LE. Add
the die-cut 1/8" balsa
fin TE spar and align it over
the plan. Glue the ribs to the fin TE spar.
❏
3. Sand the LE of the fin ribs to the angle of the
LE on the plan. Cut the fin LE from the 3/8" x 1-3/4"
x 12" balsa stick. Glue the fin LE to the front of the
ribs. Trim the left side of the fin LE to within 1/8" of
the upward facing (left side) of the ribs.
