Step 53 - Fuselage Assembly (F1)
Locate F1 from LP1. Note that one side has
several markings etched on it. This side we
refer to as the “electric” side. The smaller
holes line up with our motor mount box
(shown later) and the six larger holes are
recommended spots where you could drill
holes to allow air to cool the batteries/ESC.
If you are going electric, glue this piece in
place with the etching facing outward.
If you are going glow, disregard all of this
by flipping the piece over and gluing the
etched side to F2.
Regardless of the way you go, we recommend epoxy for this step.
Step 54 - Fuselage Assembly (F0)
Locate FS0 from LP3 or LP4 as
this will be used as the other
side of the fuselage front
section.
As before, we recommend dry
fitting this first so you can see
that all of the tabs fit in to all of
the slots.
When you think you have it
figured out, glue the back edge first - gluing F5 to the side and just
a little bit of T2, where it touches T1.
Once the glue has cured, then tackle the front section. You’ll
probably need to hold/clamp it in place while the glue cures.
Step 55 - Fuselage Assembly (balsa sides)
Locate FS1 from BP4, FS2
and FS4 from BP5 and FS3
from BP6. These four pieces
are assembled to create a
finished fuselage side.
Glue FS1 to FS2 first, then
add FS3 and finally FS4.
Make sure these pieces are
absolutely flat where they
join so you end up with a smooth side. When finished, repeat this
step to make the other balsa fuselage side.
Step 56 - Fuselage Assembly (balsa sides)
These next two steps
are more critical than
most in the construction
of our Javelin. That’s
because there are no
slots or tabs to aid in
alignment. It’s all up to
you so get it right the
first time as it’s very
hard to fix any problems
once the glue cures.
Take one of the balsa sides from the previous step and you will now
glue it to one of the sides of the plywood assembly. Be careful to
line it up exactly and make sure it stays in place as the glue cures.
Step 57 - Fuselage Assembly (balsa sides)
Just as in the last step, take the
other balsa side and glue it to
the other side of the plywood
assembly. Be careful to line it up
exactly and make sure it stays in
place as the glue cures.
When finished you will have a
fuselage assembly as shown here.
Step 58 - Fuselage Assembly (side alignment)
Using a couple of t-pins, pin the rear of the
balsa sides together as shown. Don’t glue
them - just pin them together so they remain
perfectly aligned for the next few steps.
Step 59 - Fuselage Assembly (F6)
Locate both halves of F6 from BP7. Glue
them together to form a completed piece.
Then cut two small strips of scrap 1/8”
balsa to form the vertical doublers. No
specific dimensions are needed, just as
long as they are similar to what’s shown
here. Glue these in place to strengthen F6 along it’s sides.
Step 60 - Fuselage Assembly (P6)
Now carefully fit the completed F6 into
place. Glue it securely to both sides of
the fuse, making sure that it is firmly
seated in the notches of the fuselage
sides.
Step 61 - Fuselage Assembly (F7 & F8)
Locate F7 and F8 from BP7. Similarly to
what you just did for F6, cut some scrap
1/8” sheet to form a top and bottom
support for both of these pieces. This
time the supports will run across the
pieces.
Glue them in position.
Step 62 - Fuselage Assembly (F7, F8 & F9)
Along with F7 and F8 from the
previous step, locate F9 from
BP5. Starting with F7, carefully
place it in position, making sure
it is securely glued to both sides
of the fuse and firmly seated in
the notches of the fuselage sides.
Then attach F8, and finally F9.
Step 63 - Fuselage Assembly (tailwheel support)
Locate TW1 from LP2 and both TW2s from
LP1 and LP5. These three pieces are glued
together as shown here to form the thick
support needed for some tailwheel mounts.
Note that these pieces should be flush on the
short end, with the TW2s, centered side to side on TW1.
