Prepare Firewall; Assemble The Fuselage - GREAT PLANES FUN-ONE Instruction Book

D 5. Go back to step 1 and assemble the other fuselage
side. BE CAREFUL TO ASSEMBLE A RIGHT AND
A LEFT FUSE SIDE. DO NOT MAKE TWO EX-
ACTLY ALIKE!!!
D 6. Glue former F4B (FUN1F09) on former F4A
(FUN1 F08) lining up the edges as shown in the photo.
PREPARE THE FIREWALL (Fl)
D 1. Use a straight edge to draw two crossing lines
from corner to corner on the FRONT face of former Fl
(FUN1 F20). Refer to the fuse side view on the plans to
determine the front of the firewall. Position the engine
mount (MM 19D90) against former Fl so that the crossing
lines arc visible through each of the four engine mount
holes. This will automatically center it. Hold it in place
and use a nail to make a mark in the center of each hole.
D 2. Remove the engine mount and drill 9/64" holes at
the bolt locations, then install the 4-40 blind nuts (NUTS001)
on the BACK of Fl. Press the blind nuts in with pliers, or
tap them in with a hammer.
D 3. Temporarily attach the engine mount to the fire-
wall with the 4-40 x 5/8" bolts (SCRW052). Use the bolts
to help pull the blind nuts into place. If you are using a
different mount and more than 1/8" of the bolt protrudes
through the firewall, you should cut off the excess bolt length.

ASSEMBLE THE FUSELAGE

D 1 Lay the two fuselage sides down flat on the work
surface with the doublers facing up. Trial fit formers Fl,
F2A, F3, F4A/B, F5 and F6 (from FUN1FO8 AND
FUN 1 F09) in place on both fuse sides.
D 2. Using #64 rubberbands to hold everything to-
gether, assemble the fuse sides along with the formers and
the 1/8" die-cut balsa rear fuse bottom (FUNF04)) and
the 1/8" die-cut plywood front fuse bottom (FUN 1 F09).
