Refer to these photos for the next four steps.
Disregard the servos.
10. Glue the 3/16" x 1/2" x 9-7/8" balsa bottom
fuse sheeting support in position. Sand the ends
even with the fuse side doublers. Cut and fit, but
do not glue, the aft bottom fuse stringers from
seven 3/16" x 3/16" x 36" balsa sticks to fit in the
notches of the formers as shown on the plan and in
the photo. Save the leftover pieces. The three
bottom stringers extend to the sheeting support.
You can see the stringers in the photo at step 5
page 38.
11. Glue the fronts of the three bottom stringers
to the sheeting support, then use your 90 degree
triangle to hold each former at the correct angle
and glue the bottom stringers to the formers.
12. Glue the 3/16" x 3/16" side stringers and
pushrod guide tubes to the formers.
13. Cut the bottom corner stringers to fit on the
formers where shown on the plan from two 1/2" x
36" balsa triangle sticks. Glue the corner stringers
in place.
MOUNT THE SERVOS
1. Optional: For routing your receiver antenna
out the back of the fuselage, cut a third 3/16" outer
pushrod guide tube (not included) to
a length of
21". Roughen the outside of the tube with coarse
sandpaper
(so glue will stick) and slide the tube
through the holes in the bottom of the formers until
the front extends past former F7 by approximately
1/2". Glue the tube to the formers (this tube is
visible in the photo at step 5).
2. Test fit your servos in the aft servo trays
(or ruddervator/elevator servo trays) to make sure
they fit. Glue a servo tray doubler to the bottom of
the front of both trays.
3. Cut an aft servo tray rail from a 1/4" x 3/8" x
36" basswood stick to fit between the fuse sides
approximately 1-7/8" aft of former F5 where shown
on the plan. It will be helpful if you cut the rail to a
length that will provide a friction fit between the
fuse side doublers so it will temporarily stay in
position without using glue. Position the aft servo
tray rail between the fuse sides.
4. Position your servos into the servo trays and
place the trays on the rail and former F5.
Temporarily thread two nylon clevises just a few
turns onto two 36" one-end threaded pushrods.
Install the pushrods into the pushrod guide tubes
and connect the clevises to servo arms on
your servos.
5. Position the rail and the servo trays so the
servo arms align with the pushrods. Glue the rail
and servo trays to former F5 and the fuse sides in
this position. Drill 1/16" holes in the servo trays and
mount the servos with the screws that came with
your radio.
FINISH FRAMING THE FUSE
1. Refer to the photo in the following step and
test fit a die-cut 1/8" balsa forward fuse doubler
on the right side of the fuse. The front edge of the
forward fuse doubler should align with the front
edge
of the fuse side doubler. Wet the outer
surface of the doubler and glue it in place. Be sure
that former F2 remains square and flat.

2. Glue the other forward fuse doubler to the left
side of the fuselage. Use 3/16" x 3/16" balsa sticks
leftover from the aft bottom stringers to make the
forward bottom stringers that fit in the notches of
the firewall and F2. Glue the stringers in place.
