Construction
Wing
The wing is a fully-sheeted spar-less design that achieves
strength without unnecessary weight. The wing is designed
to be permanently attached to the model’s fuselage for
structural integrity.
The wing consists of two panels: port and starboard. Each
panel has a top skin and a bottom skin.
Wing Skins
Each lower wing skin consists of two laser-cut and
etched pieces: forward and aft. Gently clean up the
mating edges of the skin pieces with 220 grit paper
on a sanding block.
Lay the two pieces of a wing skin on a flat board or
table, with the outer surface up. Run a length of
masking tape along the join line. Turn the assembled
skin over, bend the joint open, and run a bead of
wood glue down the joint.
Lay the assembled skin back down on the flat board
– masking tape side down. Run a damp paper towel
over the joint to remove excess glue. Place a sheet
of wax paper over the assembled skin. Then weight
it down with another board, books or what have you.
Keep the weight on the skin until it is completely dry.
While waiting for the bottom skins to dry, prepare
the top skin material as follows. For each top skin,
join two sheets of 1/16” x 4” balsa using the tape
and glue method above.
When the bottom skins are dry, remove the masking
tape from the joints.
Trace the outlines of the bottom skins onto the top
skin material. Then cut out the top skins leaving
about 1/8” extra material at the trailing edges.
Sand each skin as follows. Lay a skin on a flat board
with the outer surface up, and sand it smooth with
120 grit paper on a long sanding block. Be sure to
keep your sanding motion at a 45-degree angle to
the joints and wood grain. Clean the skin with a tack
rag.
Note – it should not be necessary to sand the inner
surfaces of the wing skins. Just be sure to remove
any excess glue.
