The Wee Bee was designed by William "Bill" Chana, Kenneth Coward, Karl Montijo and Jim Wilder, who designed the engine. They described it as big enough to carry a man and small enough to be carried by a man.[1]
It was an all-metal cantilever mid-wing monoplane powered by a Kiekhaefer O-45-35 flat-twin piston engine.[1] It had a conventional tail and fixed tricycle landing gear.[1] The unusual feature was that the aircraft lacked any internal room for a pilot who had to fly it lying prone atop the fuselage.[1][2]
