FINISH THE FUSELAGE
❏ 1. Glue the die-cut 1/8" [3.2mm] ply former F3T
into place on the top deck using thin CA. Make sure
that it is perpendicular to the top deck and that it is
centered between the sides, directly on top of F3.
❏ 2. Glue die-cut 1/8" [3.2mm] ply formers F3TR,
F4T, F4TR, F5, F5TR and F6 into position using the
marks you made earlier. Make sure the formers are
perpendicular to the top deck and are centered
between the sides.
❏
3. Glue a 3/16" x 3/16" x 24" [4.8 x 4.8 x 610mm]
balsa stick from F3T to F5TR. As you glue the stick
to each former make sure the former is
perpendicular to the top deck. Trim the stick even
with F3T and F5TR.
❏ 4. Glue two 1/8" x 1/8" x 24" [3.2 x 3.2 x 610mm]
balsa sticks from F3T and F6T along the top of the
top deck. Trim the sticks even with F3T and F6T.
❏ 5. Use a bar sander with 150-grit sandpaper to
blend the sticks with the shape of the formers.
❏ 6. Glue die-cut 1/8" [3.2mm] ply formers F1T,
F1TR, F2T, F3TC and F3TF in place to the top deck.
Make sure the formers are perpendicular to the top
deck and are centered between the sides.
❏ 7. There are three other formers that are supplied
and are shown in the next photo. These are F2TX and
two F3TX. These formers are shown on the side view of
the fuselage plan. The location of these formers
depends on the location of your servos and receiver.
They are used to prevent the top sheeting from sagging
between the other formers. Glue F2TX and both F3TX
formers in place as desired.
❏ 8. Glue a 3/16" x 3/16" x 24" [4.8 x 4.8 x 610mm]
balsa stick from F1T to F3TF. As you glue the stick to
each former make sure the former is perpendicular
to the top deck. Trim the stick even with F1T. Use
your bar sander to blend the stick with the shape of
the formers.
Note: If you installed full size servos you will need to
trim the stick where it crosses the servos.

9. Mount your switch to the side of the fuselage.
We used a Great Planes Switch/Charge Mount
(GPMM1000). You will need to cut a hole in the top
deck for the switch. We installed the mount on the left
side of the fuselage as it is easier for a right handed
person to reach it. You may want to mount it on the
left side to keep it away from the engine exhaust.
Make sure the mount and switch will clear the wing
when it is mounted to the fuselage.
