Variously known as "Przasnicza", "Don
Kichot", or "Don Quixote", the J-1 was designed by Jaroslaw Janowski in
1967. It featured a single seat enclosed cockpit, conventional
(taildragger) landing gear, and a pusher prop configuration. Wings were
shoulder mounted and strut-braced, with a 13% thick Clark "Y" airfoil
and no flaps.
With the help of Witold Kalita, the prototype was constructed in
Poland and first flown on July 30, 1970. It weighed 286 lbs empty, and
was constructed mostly of wood with a steel tube frame and fabric
covering. Wings were constructed with one-piece ribs and a plywood
covered leading edge "D-section". Power was provided by a two cylinder
23 hp "Saturn 500B" engine which was also designed by Janowski and
constructed by S. Polawski.
