2. Locate the two die-cut 1/8" [3.2mm] balsa upper
fuse deck halves. Glue them together and then pin
them over the fuselage bottom view.
3. Drill a 3/16" [4.8mm] hole in the punch marks on
formers F-2A, F-2B, F-4A and F-5A. These will
accommodate the pushrod installation as we build
the fuse.
4. Locate the 1/8" [3.2mm] die-cut ply former F-2A
and F-2B. Use 6-minute epoxy to glue F-2B to F-2A,
aligning the 1/4 holes in the formers.
5. Test fit formers F-2A, F-3A, F-4A and F-5A into
the slots in the upper fuse deck with the lettering
facing forward. Use a small triangle to make sure the
formers are perpendicular to the upper fuse deck,
then glue the formers in place.
6. Locate the die-cut 1/8" [3.2mm] balsa lower
aft fuse doubler (LAD), upper aft fuse doubler
(UAD), lower fuse doubler (LFD) and the upper
forward fuse doubler (UFD). Glue them in place on
the die-cut 3/32" [2.4mm] balsa fuselage side. The
doublers should be positioned so the tabs on the
front of the doublers are flush with the fuse front. Be
sure when you glue the doublers to the fuselage side
that you make a left and right fuselage side.
7. Repeat step 6 for the other fuselage side.

8. Glue the left fuselage side in place on the upper
fuse deck and to each of the fuselage formers. Do
the same for the right side of the fuselage.
9. Use some 120-grit sandpaper to roughen the
plastic outer pushrod tubes where they will come in
contact with the fuselage formers and the slot in the
side of the fuselage. Working from the open fuse
bottom, route the tubes though the F-4A, F5A and the
fuse sides. Make sure both pushrod guides extend
1/2" as shown. The tubes should also protrude at least
1" from the fuse side exits. Glue both pushrod guides
to each former and the fuse side.
10. Fill any gaps around the outer pushrod guide
tubes with a lightweight filler such as Hobbico
