well as both pre-bent landing
gears.
You will now bolt one WB5/WB6
assembly to each landing gear.
When properly installed, the
notches in WB5 will be visible, as
shown here. Take care to make
sure these fasteners are tightened, but not overly tightened so
they don’t start crushing the plywood.
Step 95 - Main Gear Assembly (WB7)
Locate WB7 from LP1 and two
#4 washers from the hardware
bag. Use a drop of CA to lightly
glue one washer to each end of
WB7, surrounding the pre-cut
mounting holes as shown.
Step 96 - Main Gear Assembly (WB3 & WB8)
Locate both WB3s from LP2 and
WB8 from LP1. These pieces, along
with the WB7 assembly from the
previous step are now assembled as
shown here.
First push the tabs of WB7 into the
notches of each WB3. WB7 should
be oriented so the side with the
washers faces the non-tabbed side
of each WB3.
When assembled, then push this assembly into the slots cut into the
middle of WB8. Make sure these are all fully seated, perpendicular
to each other and firmly glued in place.
Step 97 - Main Gear Assembly (WB4)
Locate the both WB4s from LP2.
These are glued in position on the
outer rows of pre-cut slots in WH8.
Note that this photo shows WH8
which is wider than your piece.
This was a prototype part that was
actually cut too wide. The narrower
part you have is the correct one.
Step 98 - Main Gear Assembly (WB4)
Now the three main assemblies
are glued together.
Glue one WB5/WB6 assembly
to each side of the landing
gear box, making sure all of the
tabs are firmly seated. It might
be wise to use a clamp to hold
these assemblies in place.
Also note the orientation of the landing gear and both should
extend the same way.
Make sure these pieces are firmly glued together. We also
recommend wicking in a bit of thin CA to harden up all of the
plywood.
Step 99 - Main Gear Assembly (WB11)
Locate both WB11s from LP3 and LP4.
These are positioned as shown
here, and the etched in arrow
(not shown in the picture)
should point towards the
outside of the box.
You’ll also notice when looking
into the hole, you should be
able to see through the other holes in WB7 and WB8.
Step 100 - Main Gear Assembly
.
Locate two WB12s and two WB13s from
LP3 and LP4.
WB12 is glued to both sides of the
aluminum landing gear, allowing the
heads of the 4-40 bolts to slide into
WB12’s pre-cut holes.
WB13 is glued on to WH12 to expand
the width of the landing gear box to the correct size.
Step 101 - Main Gear Assembly
Now the finished main gear box can be installed into the bottom of
the fuselage.
Note you’ll have to sand off a bit off the leading edge
of both WB13s so the box will slide into the fuselage (accounting
for the taper of the fuse sides). You want this to be a very snug fit,
but not so much that it bulges
the fuselage sides.
Locate both 4-40 x 1-1/2” bolts
and two 4-40 t-nuts from the
hardware bag.
Insert the assembled landing
gear box into the fuselage,
paying attention to the angle of
the main gear as the rear edge
should sweep slightly forward.
Slide both 4-40 bolts into the
mounting holes of the box and
the screws will extend into the
cabin area of the fuselage. Now thread both t-nuts on the bolts as
shown here. Tighten the bolts to fully seat the t-nuts in place. You
can secure the t-nuts with a few drops of glue, but make sure not
to get glue on the threads.
This completes major
assembly of the Javelin.
You should now have an
airframe that looks pretty
much like this:
Step 102 - Fuselage Assembly (front sheeting)
We’re going to show you this step
now, but it’s probably best that
you don’t do it until you’ve figured
out everything happening around
the firewall and mounting your
choice of power.
It is strongly recommended that
