Construction Manual
Round the leading edge of the stab as well as the trailing edges of
the elevator and rudder. When rounding the leading edge of the
vertical fin, only round down to the mark you made earlier, where
RD1 will attach.
Sand bevels into the leading edge of both elevator halves and the
rudder.
Step 85 - Fuselage Assembly (stab alignment)
Although we’ve
done everything
possible to
engineer the Javelin so it will build straight and true, take a few
minutes to guarantee things are straight before gluing on the tail
surfaces.
First bolt on the wing. Now, to align the stab, slide it in place. Look
at the fuselage straight on, from the nose (or tail) and make sure
that the stab is level with the wings. If not, remove the stab and
gently sand the stab supports a little at time. Check the stab and
re-sand the supports as needed.
Step 86 - Fuselage Assembly (stab alignment)
Once leveled, ensure that the stab is
aligned with the wing by measuring the
distance from the left wing
tip to the left tip of the
stab. Compare this to the
distance between the right
wing and right stab tip. Slide
the stab a bit until these two
measurements are equal.
When aligned, you should also see
that the pre-cut slot in the middle of
the stab is centered in the fuselage.
Make a couple of marks where the stab touches the fuselage so
you can place it back in the same position.
Remove the stab, apply glue on the stab supports then attach the
stab in place.
Step 87 - Fuselage Assembly (stab/fin installation)
The vertical fin’s tab will slide
through the fuselage and down
into the slot pre-cut into the stab.
Sand the fin if necessary to get a
firm, slop-free fit. Also ensure that
the fin is perfectly vertical (90° in
relation to the stab).
Mark and trim the 1/4” framing so
it will allow the rudder to clear.
Once properly in position, it’s time to glue the stab and fin
in position. Take a bit of time to make sure all glue joints are
sufficient, but don’t use too much glue as it will make the Javelin
unnecessarily tail-heavy.
Step 88 - Fuselage Assembly (P3)
Locate both P3s from BP5. These are
glued on the top of the fuse, to the left
and right of the vertical fin, completing
the sheeting.
Once glued in place, sand these pieces
to blend into the fuselage.
Step 89 - Fuselage Assembly (RD1)
Locate both RD1s from BP3. Glue
these together, then glue the
assembly in place as shown here.
Make sure it is straight when
attaching. Then sand to blend into
the vertical fin.
Step 90 - Fuselage Assembly (elevator joiner)
Locate the pre-bent elevator
joiner from the hardware bag.
Make sure that this piece is
perfectly flat as it can twist a bit
with temperature changes.
Temporarily tape the elevator
halves in position on the stab.
Now place the elevator joiner
on top of the elevator halves and mark where holes will need to be
drilled (approximately 1” in from the inside edge).
Remove each elevator half and carefully drill a hole at these
marked locations with a 1/8” drill bit. The hole should be roughly
3/4” deep and straight into the wood. Take care to not drill in at an
angle or you risk the chance of the bit cutting through the surface
of the piece.
When finished drilling, use a hobby knife to cut a channel just wide
and deep enough for the joiner’s wire to seat properly.
After you’ve completed this for both halves, use a bit of medium
CA glue to permanently glue the joiner into both halves - making
sure the completed leading edge of the elevator is perfectly
straight and flat.
This completes major assembly of the Javelin airframe.
Now it’s time to start construction of the main gear box.
Step 91 - Main gear (axle hole)
Locate the main gear halves from the
hardware bag. Each of these need a
5/16” hole drilled into the bottom
bend, as shown here. This will allow
the axle shaft to be inserted in the
next step.
Step 92 - Main gear (attach axle)
Locate the axle shafts and their matching
locknuts. These are now attached to the
landing gear halves as shown. Make sure the
lock nuts are tightened firmly.
Step 93 - Main Gear Assembly (WB5/WB6)
Locate both WB5 and WB6 from
LP1 and LP2. These are glued
together to make two WB5/WB6
assemblies.
When gluing them together make
sure the holes are aligned between
the two pieces and that the outer edges are also aligned.
Step 94 - Main Gear Assembly (WB5/WB6)
Locate six 4-40 bolts and six lock nuts from the hardware bag as
