Fiber Wing Spars
Shark II 2PT hollow, tapered carbon wing spars. Length is
32.5 inches. Weight is 9.0 grams. Tapers from 0.285 inches
at the base to 0.220 inches at the tip. The wrapped carbon
tubes are much stronger and lighter than "pultruded"
tubes, and they don't cost that much more. They fit on our
machined aluminum servo arm
or the ornithopter gearbox.
Spar - 12.95 ea.
