The wing is built from solid, light grade 1/4" thick balsa. It has 28 inches of span.
There is a 3/16" x 1/4" spruce spar that is about 14" long to reenforce the wing.
Flat bottom airfoil, I just round off the top side to a nice smooth contour.
The engine is a 1cc Cyclon with 4.2x4 prop.
A pair of HS65 servos to control elevons.
The whole thing weighs about 14 ozs with a 350 mah battery and micro RX.
