The Birdman Project 102, also known as Windsoar, was an experimental high wing, single engine, pod-and-boom, conventional landing gear-equipped, ultralight motor glider originally intended for production by Birdman Enterprises.
The all-metal wing was cantilever, stressed to +6/-6 g and featured full-span reflexing ailerons that could be raised to increase cruise performance, as well as winglets.
The cockpit included a windshield, with the sides left open, although a full enclosure was intended to be optional.
[1] The Windsoar was planned to be delivered to buyers as an assembly kit that would take about 100–200 hours to complete.
[1] Project 102 was supposed to fly in the summer of 1982, with kit production commencing the following autumn and winter and customer deliveries in the spring of 1983.
