• Pushrods (two 5” for ailerons, two 24” for elevator & rudder,
one 12” for throttle if glow/gas powered)
• Clevises for the pushrods (8 if electric, 10 if glow).
• 2 - 3.5” diameter wheels
• 1 - tailwheel assembly
• Covering
• Optional - 2-1/2” spinner
Additional Required Building Tools and Adhesives
• Drill & assorted drill bits
• Hobby knife and new, sharp blades
• Sandpaper: coarse (80 or 100 grit) & medium (150-200 grit)
• Pencil or pen
• Ruler
• String (two 18” lengths)
• T-Pins
• Waxed paper
• Building board
• Adhesives of your choice. We recommend thin and medium
CA (cyanoacrylate) viscosities, and 15 or 30 minute epoxy
• Epoxy brushes and mixing sticks
• Threadlocking compound
Before Starting Assembly
Closely inspect the supplied laser cut parts for damage. If you find
any damaged or missing parts, contact us immediately.
When removing the laser cut parts from their sheets, you’ll notice
the parts are held in place by several small “tabs”. These tabs
are uncut pieces of wood and can sometimes make it difficult to
remove a part. Rather than breaking and/or splintering the wood
by forcing out the part, we recommend removing any laser cut
parts from their sheets by using a hobby knife with a new, sharp
blade. A quick cut of the tab will allow the piece to be removed
with no damage. Sand any tab remainders flush with the part so
there will be no problem aligning them later.
It’s best to not remove parts from their sheets until they are needed.
Refer to Appendix A of this manual as a reference to what all the
laser cut parts look like and are called.
For each step, we highly recommend that you dry fit the parts in
each step first. Lightly sand as needed to ensure a good fit. Once
you’re satisfied with the fit, then and only then, glue the parts in
position.
IT IS VERY IMPORTANT THAT YOU ASSEMBLE THIS JAVELIN
KIT IN THE ORDER DESCRIBED. SKIPPING FORWARD IN
THE STEPS COULD LEAVE YOU WITHOUT THE PROPER
LENGTHS OF WOOD TO FINISH THE KIT.
WE’VE INCLUDED ENOUGH WOOD TO EASILY COMPLETE
THIS KIT, BUT YOU MUST TAKE CARE TO PROPERLY
MEASURE AND NOT WASTE WOOD WHEN CUTTING.
Closely inspect the supplied laser cut parts for damage. If you
find any damaged or missing parts, contact us immediately.
Let’s begin construction by working on the Javelin’s wing. The
wing is built with top surface resting on your building board
(up-side-down). Also the left and right halves are built at the
same time, so you’ll need to perform each step on one side
of the wing first (say the port side), then perform that same
step on the other side (the starboard side).
However, take care as the layout of the ribs will be mirror
image from one side of the wing to the other.
Step 1 - Alignment triangles
Pre-cut into BP6 is a triangle that can be
used to vertically align any of the parts
in the construction of your Javelin. BP6
also includes a foot piece that can be
used with the triangle to hold it vertically,
hands-free.
We recommend using this triangle throughout the wing
construction, and in the alignment of the vertical fin.
Step 2 - Prepare your work area
You’ll need a flat building surface that is a
minimum of 60” long as the wing is built as
a single piece, not two separate, then joined
assemblies.
Position the wing plan over the surface and
tape into position. Tear off a length of waxed
paper long enough to cover the plan and
tape that into position, over the plan.
Step 3 - Wing Assembly (upper spar)
Locate two of the 3/16” x 3/8” x 36” basswood strips. These will
form the upper spar. Position them over the plan, measure the
length and cut. We prefer to tack-glue these pieces to the waxed
paper, holding them in place using a few small drops of medium
CA, instead of t-pins. Be sure they are aligned properly and are
straight over their entire length. The alignment of this spar is critical
as the rest of the wing panel is based off these two pieces.
Step 4 - Wing Assembly (R1)
Locate both R1s from LP1. These are glued together to make a
thicker piece. We recommend
using epoxy for this step and
be careful not to let any of the
adhesive get into the slots around
the perimeter of the rib, as this will
cause problems when fitting the
