Wings first: I cut the plugs off
the molded Styrofoam wings in a single stroke
that goes at a right angle to the trailing edge.
I angled the blade slightly to induce the 1”
of dihedral. Putting the two wing halves together
was simple...a butt joint with aliphatic resin,
then cellophane tape spanwise from tip to tip,
top and bottom, 1.5” from the trailing edge,
and a 2.5” piece top and bottom 3”
from the trailing edge. The left wing features
1/32” ply discs, glued with foam-safe CA,
as reinforcement for the discus launching peg.
The wing mount was the most difficult part of
the build. I built up a ¼ x 3/8”
triangle fillet on each side of the wing half.
This is a fragile piece as the grain runs spanwise.
I’m not sure, but I sense that it might
work better with grain running fore-aft like typical
triangle stock. Unlike triangle stock, however,
the fillets are not right triangles in cross section.
Their angles fit the wing and wing pylon exactly.
The wing pylon is light 1/8” balsa with
grain running up-down.
The forward fuselage uses light 1/8” balsa
with grain running fore-aft. The front piece is
an expendable piece of 1/8” balsa. This
is like a car bumper. It is smooshed in a crash,
reducing damage to the rest of the airplane, and
easily replaced. The battery and received are
taped to the forward fuselage using double-sided
foam tape. The granola bar wrapper, trimmed to
the shape shown on plan, is slipped over this
and taped to the top of the wing.
