Construction Manual
Step 64 - Fuselage Assembly (tailwheel support)
The tailwheel support assembly is now glued
in place, on the underside of the fuse, at the
rear.
It is positioned so the TW2s are inside the fuse
and TW1 is resting on the sides, as shown here.
Glue this in place, while also gluing the balsa
sides together.
Step 65 - Fuselage Assembly (1/4” square)
Now you will begin “framing” the
perimeter of the fuselage sides,
starting with the longest lengths
first. Place the fuselage so it is up-
side-down on your building surface.
Measure and cut two lengths of 1/4”
square balsa to form the rear framing.
These pieces should run from the tailwheel assembly up to F3.
When gluing these in place, make sure the strips are fully inserted
into the notches of F4-F9 and follow the curvature of the fuse sides.
Step 66 - Fuselage Assembly (1/4” square)
Flip the fuselage over to cut the next
longest pieces, the top of the rear fuse.
These pieces should run from the rear of
the fuse up to F6.
When gluing these in place, make sure
the strips are fully inserted into the
notches of F6-F9 and again follow the
curvature of the sides.
Also you’ll need to cut a relief in both pieces where the meet at
the rear of the fuselage. Cut just enough away so you can properly
glue on the framing. They will be properly trimmed for the vertical
fin clearance later on.
Step 67 - Fuselage Assembly (1/4” square)
Flip the fuselage up-side-down for the
next pieces, the front of the fuse. These
pieces should butt against the 1/4 sq.
sticks already installed (at F3) up to the
front of the fuselage sides (leaving an
extra 1/8” or so for final sanding).
When gluing these in place, make sure
the strips are fully inserted into the notches of F1-F3.
Step 68 - Fuselage Assembly (1/4” square)
Flip the fuselage upright again for the
last of the framing at the front of the
fuse and just behind the wing saddle.
Again, when gluing these in place,
make sure the strips are fully inserted
into the notches of the formers.
Step 69 - Fuselage Assembly (P1 & P2)
Locate P1 and P2 from LP2. These are
glued in place on the underside of the
fuselage as shown here. Make sure they
do not overlap into the landing gear
mounting box.
Step 70 - Fuselage Assembly (bottom sheeting)
Now locate the un-cut sheets
of 1/8” x 4” balsa. You will use
these to form the sheeting for
the bottom of the fuselage. The
sheeting is cut so it is cross-
grained (running from side to side
for strength).
Starting at the rear of P2, measure,
cut, and glue strips to form the
bottom of the fuselage. Make sure that the sheeting is not only
glued to the 1/4” framing, but also to each other as you work your
way back 4” at a time. Stop when you reach the end of the framing
at tailwheel support.
Step 71 - Fuselage Assembly (top sheeting)
Now, flip the fuselage over and
sheet the top of the fuselage in the
same way, starting at the rear of the
wing cutout, backwards - to just
forward of F10, as shown here.
Step 72 - Fuselage Assembly (hatch)
Locate H1 from LP6, two H2s and
two H3s from LP5. Also locate
two of the 1/4” magnets from the
hardware bag.
First, push the magnets into the
holes of both H2s, make sure they
are fully seated. A gentle tap should
be all that’s needed to hold them
securely in position.
Now lay H1 flat on your work surface. Glue both H2’s in place, on
the narrow end of H1. Make sure both are at 90° angles to H1.
Next glue both H3s in place, again at 90° angles and making sure
the flat end of each H3 is pushed completely into the slots of H1.
Lastly, cut two strips of scrap 1/8” ply to run from side to side as
shown in the photo. These will add support and stiffness to H1.
Step 73 - Fuselage Assembly (hatch)
Locate the remaining two magnets
from the hardware bag. These two
magnets are pushed into the pre-
cut holes in the fuselage sides, just
aft of the firewall.
When pushing these in place,
remember that magnets attract in
one way only. Putting them in the
wrong way will leave you with a hatch that will never close.
This completes major assembly of the Javelin fuselage.
Now it’s time to start construction of the tail surfaces.
Prepare your work area
Now tape the horizontal stabilizer plan and a fresh piece of waxed
paper on your building board.
