Step 91 - Fuse Assembly (F1)
Locate both F1s from LP1 and LP2. Note there
one large and two smaller cutouts in each, as well
as an "X" pattern etched into the center.
Mix up a bit of epoxy to glue these two pieces
together, making sure that at least one of the
"X" etched faces is visible. Both pieces should be perfectly aligned and
clamped/weighted-down while the glue cures.
Remove any excess glue from the center cutout as well as the two smaller holes.

Step 92 - Fuse Assembly (F1)
Before attaching the F1 (firewall) to the front
of the fuselage, take a few minutes to sand the
front face of the fuselage smooth. Remove the
fuselage from the board first, then go over it to
remove any excess glue, framing, etc.
Once sanded, its time to attach the F1 assembly
to the fuselage. Mix up some epoxy and apply
it around the edges where F1 contacts the fuselage framing and side
sheeting.
Attach the firewall, making sure the two small holes are towards the
bottom, and the etched "X" faces outwards. Use tape or clamps to hold
this securely in place until the glue cures.
n
Step 93 - Fuse Assembly (upper cross-framing)
Using more of the 3/16"
sq. balsa sticks, it's time
to measure, cut and glue
in some of the upper
cross-framing.
Attach the piece across
the rear of the wing saddle, the doubled-up pieces just aft, and then
the piece that's at the rear of the side sheeting.
n
Step 94 - Fuse Assembly (align fuselage sides)
This is gonna look a little strange, but it
really helps to align the fuselage sides,
and keep them that way while you
install the rest of the fuselage cross-
framing.
Locate the vertical fin you made way,
way back. Tape this in place at the
back of the fuselage, between the side
frames like is shown here. Eye down
the length of the fuselage to make sure that both sides have a
nice, straight taper back to this point -
no banana-shaped stuff here
please. Now, be careful over the next couple of steps because you
don't want to break off the fin before you get a chance to use it!
n
Step 95 - Fuse Assembly (cross-framing)
Using more of the 3/16" sq. balsa stick, now measure, cut and glue
in the rest of the fuselage
cross-framing. Remember
that matching sets of braces
goes on the top and bottom,
so take your time and get
this right. Again, this part will
show, so make yourself proud
here.
n
Step 96 - Fuse Assembly (Tail-skid mounts)
Locate LG3, both LG4s , LG5 and
both LG6s from LP6. LG3 and LG4
make up the forward mount, with LG5
and LG6 making up the aft mount.
Note that these all have etched
circles which - say it with me.....marks
the front edge.....nicely done.
Refer to the plans as for the exact
placement of LG3 and LG5 as they are
attached first, glued to the bottom
of the fuselage, with their outer
edges flush with the outer fuselage
framing. Then the pairs of LG4 and
LG6 are glued on top, in between the
fuselage framing to thicken up these
mounts.
n
Step 97 - Fuse Assembly (H6, H7)
Locate all of the H6s and H7s from LP5.
They might look the same, but there's a slight difference between
the two parts, so don't mix them up.
These pieces are will be used as attachment points for the back
two fuselage hatches.
Let's start with the H6s first. You can either glue two of them on
top of each other, then glue them in place, or glue one in place
on the fuselage, then the other below
it - your call.
What you're shooting for with the H6s
is to have them in the front two corners,
up against the side and cross-framing.
And at the same time, flush with the
side sheeting. Do the top two, then flip
the fuselage over and glue in the bottom two.
The use the same technique to glue in the H7's into the rear spots
- two up top, two below.
n
Step 98 - Hatch Assembly (H1, H2)
Locate H1 from LP7 and both H2s from
LP5.
If there's a bow in H1, it's best to have the
concave side face up because it will act
more as a "spring" to help hold the latch
tight against the fuselage later on.
So now that you're armed with this valuable knowledge its' time to
attach both H2's. The should be attached to the underside of H1
by gluing them into the pre-cut slots towards the front of H1. Make
sure H2's tabs are fully inserted into H1 and the "hooks" face the
front of H1, as shown here.
n
Step 99 - Hatch Assembly (H4)
Locate H4 from LP7 and H3 from LP4.
H4 serves as the
"instrument panel" on the
hatch and H3 supports it.
H3 has an etched arrow
pointing which way is up,
and coincidentally to the
edge that should be glued to H4. But before doing that, sand a
bevel into the base of H4 as shown here. It should be even across
