Watson Windwagon

The original Wind Wagon was built in Texas by Gary Wilson and was based on the Teenie Two and used the similar wing ribs that slipped onto the “C” spar. The fuselage was a tapered tube from the seat backward and from the seat to the firewall. The aircraft was equipped with tricycle undercarriage and a ½ VW.

First flown on 19 April 1977 (N64614), the Windwagon measures 18 feet from wingtip to wingtip and it features all-aluminum construction with pop rivets. The tricycle gear are nonretractable, but the wings are removable for storage or transportation. The powerplant is a 900 cc half-Volkswagen modified engine and drives a four-blade propeller. On just two cylinders tip speed is 110 mph, and climb rate is 450 to 500 fpm. The wing features a Clark Y wing section with constant chord. There are con­ventional ailerons and no flaps. The fuselage is a conventional semimonocoque structure made from pop-riveted aluminum. Morry Hummel introduced a few changes.

In 1980 full size plans were available for US$50.
