Design and development

The Windwagon is a low-wing cantilever monoplane of conventional design with fixed, tricycle undercarriage, and a single-seat open cockpit. [1] [3] Construction is of pop-riveted metal throughout. [1] The outer wing panels are removable to facilitate hangering and trailering. [1] [3] [4]

Power is supplied by an air-cooled, tractor-mounted piston engine driving a propeller. [1] The engine selected by Watson was an automotive Volkwagen air-cooled engine sawn in half across its crankcase to turn the flat-four engine into a flat-two [1] [3] [4] (a modification called a "half VW"). Plans for the Windwagon included instructions for modifying a Volkswagen engine this way. [1]

By 1987, Watson had sold over 1,025 sets of plans, and over 500 Windwagons had been built around the world. [1]

The Hummel Bird is a development of this design. [3]
