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
ROBINHOOD 80 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.
Let’s begin construction by working on the right (starboard)
wing of your Robinhood 80.
Prepare your work area
You’ll need a flat building surface that is a minimum of 40” long.
Position the starboard wing plan over the surface and tape into
position. Tear off a length of waxed paper long enough to cover
the left wing plan and tape that into position, over the plan.
Step 1 - Struts
This might seem like a strange
first step in this build, but we ask
you to do this for a reason. It’s
to guarantee that you’ll have the
proper lengths of 3/16 x 3/8”
basswood.
So, gather four pieces of 3/16”
x 3/8” and eight 3/16” square
balsa sticks. Cut a 25-1/4” length
from each piece and set the short
pieces aside to use in other steps.
Take one 3/16” x 3/8” basswood piece and lay it on your board.
Glue one of the 3/16” balsa sticks to each side of the basswood as
shown here to make one strut assembly.
To aid in keeping these pieces straight, hold the pieces against a
long straight-edge, such as a metal yard stick, while the glue cures.
Make 4 struts, then set them aside for much later on in the build.
Step 2 - Alignment triangles
Pre-cut into LP7 are two
triangles, one inside the
other. These can be used
to vertically align any of the
parts in the construction of
your Robinhood 80. LP7 also
includes two foot pieces that
can be used with the triangles
to hold both triangles vertical
hands-free.
We recommend using the smaller triangle in the wing construction
as it’s small enough to fit between the ribs.
Closely inspect the supplied laser cut parts for damage. If you find
any damaged or missing parts, contact us immediately.
