7. Line up the fuselage doublers using the
notch at their back (for F-8) and the wing saddle
as the primary references. Be sure to put them
on the inside of the fuselage sides and make a
left and a right. Glue the doublers in place with
CA.
8. Glue the die-cut 1/8" balsa Forward Fuse
Doublers in place. They should touch the
Plywood Fuselage Doublers.
9. Glue a 1/8" x 3/8" x 9" balsa Doubler Stick
along the top edge of each fuselage side
beginning at the notch in the aft fuse doubler.
Tape the Fuselage Bottom View over your flat
building board (we recommend cutting that
part of your plan loose to make it easier to
handle). Cover the bottom view with waxed
paper.
Important Note: You are building the
fuselage upside-down over the Bottom
View. This aircraft has right thrust
built in. Since the fuse is built upside-
down, this will appear to be left thrust
until it is flipped over. Just follow the
instruction sequence and everything
will be fine.
10. Pin the die-cut 1/8" plywood Forward
Crutch over its location on the plans. Make sure
the front edge of the crutch matches the plans for
the correct thrust angle.
NOTE: Some formers are not
symmetrical and must be glued in with
the proper orientation. Glue in all the
formers with the I.D. numbers toward
the FRONT of the model and they will
all be correct.

11. Drill 3/16" holes through the punch marks
in formers F-5, F-7, F-8, F-9, F-10, and F-11.
These holes are for the pushrod mounting, and
you may confirm these locations using the cross-
sections on the fuselage plans.
12. Glue the die-cut 1/8" plywood former F-5
to the forward crutch at its location on the plans.
It should be perpendicular to the crutch with its
number facing forward.
13. Glue in the die-cut 1/8" plywood former
F-7 and the die-cut 1/8" plywood Servo Tray
(ST). F-7 must also be perpendicular to the
crutch.
