tape down a fuselage length (36") of waxed paper on your work
surface so you'll have something to protect it when building the
fuselage.

Step 56 - Fuselage (FS5, FS6)
Locate both FS5s and FS6s
from LP1. One FS5 and one
FS6 are glued together to
form a fuselage side frame.
Take care of the orientation
of these pieces and make
sure the tabs in FS5 are fully
inserted into FS6's slots -
and that both pieces are flat along the entire joint. Right now, the
sides are identical so don't worry about mixing them up - that will
come later. Set these frames aside for the moment.
n
Step 57 - Fuselage (FS1, FS2)
Locate both FS1s and FS2s from
BP4. One FS1 and one FS2
are glued together to form the
forward, outer fuselage skin.
Take care of the orientation of these pieces and make sure the
tabs in FS2 are fully inserted into FS1's slots - and that both pieces
are flat along the entire joint. Right now, the sides are identical so
don't worry about mixing them up - that also will come later.
n
Step 58 - Fuselage (FS3)
Locate both FS3s from BP3. One
FS3 is glued to the rear of each
FS2.
Take care of the orientation of
these pieces and make sure the tabs in FS2 are fully inserted into
FS3's slots - and that both pieces are flat along the entire joint. Still
no worries about which side is which.
n
Step 59 - Fuselage (FS4)
Locate both FS4s from BP4. One
FS4 is glued to the bottom of each
FS3.
Take care of the orientation of
these pieces and make sure the tabs in FS4 are fully inserted into
FS3's slots - and that both pieces are flat along the entire joint. Still
no worries about which side is which.
n
Step 60 - Fuselage (sanding)
Take a few moments to lightly sand the fuselage sides and the
fuselage frames you have just created. Specifically you're wanting
the joints to be smooth and flat on both sides of each assembly.
n
Step 61 - Fuselage (frames)
Read through this step completely before even thinking of applying
glue - you've been warned!
Now you'll form the port and
starboard fuselage sides.
Shown in this picture is the
starboard side, and obviously
the port side should be a
mirror of this.
To create this, you'll glue one
of the lite-ply frames to the
Page 10
outer skin. Although there aren't tabs to do this, it easy to align
using three edges of the wing-saddle area. In the saddle, the balsa
and ply should be aligned perfectly on each edge.
When done properly, there will also be a consistent 1/4" ledge of
balsa sheeting surrounding the lite-ply frame, around the nose of
the assembly.
Again, you need to make mirror images in the step,
When you're satisfied with how these pieces are aligned, then, and
only then is it time to apply glue to the lite-ply framing and attach
it to the balsa sheeting. Take care to keep glue out of all of the pre-
cut notches in the framing.
n
Step 62 - Fuselage (FS8, FS9)
Locate four FS8s and four
FS9s from BP1. These will
form the
edging around the nose of
the fuselage.
Glue one FS8 on the bottom
and it should be aligned up
against the bottom of the
fuse frame and match the sheeting's bottom edge. Then another
FS8 on top of the FS8 you just installed.
The FS9's install similarly, just along the top edge of the fuse frame.
n
Step 63 - Fuselage (rear frames)
Locate the two 1/4" sq. x 36"
balsa strips. Using one strip,
measure and cut pieces for the
rear frames (top and bottom) -
running from F6 back to F10.
Glue these pieces in place along
the top and bottom edges of the
fuselage sheeting, up against the lite ply framing and matching the
sheeting's edges all the way back to the rear of the side.
Then do the same for the other fuse side, using the other 1/4" strip.
n
Step 64 - Fuselage (F2, F3, TR1)
Locate F3 from LP3 and F2
and TR1 from LP4.
A couple of orientation notes
here. F2 has an etched circle
which designates it's top.
Also TR1 has a "bulbous
protrusion"
words Scrabble there!). This
is at the rear of TR1.
There are two parts to this step.
First slide TR1 into the center of F2. TR1's middle notches will allow
it to slide down the sides of F2 and rest on the bottom of the cutout.
Then insert "bulbous protrusion" of TR1 into the slot cut into
the bottom of F3. Now test fit this loose assembly into the port
fuselage side, as shown in this photo.
See how all of the tabs should fit into the pre-cut slots in the
fuselage framing. Sand, file, and fit as necessary so these pieces
will all fit properly and completely into the frame.
When you're satisfied, remove the pieces, then glue them all
together, and into the fuselage side. Take your time as there's a
few things to juggle, but when finished, each piece will hold the
other at the perfect angle.
