The Janowski J1 Prząśniczka later named the Don Kichot was an ultralight aircraft designed in Poland and marketed for homebuilding in the 1970s. Designed by Jarosław Janowski in 1967 and built with the help of some friends it flew three years later. It was an unusual design with a high strut-braced wing and a pusher propeller mounted behind it. The pilot had a fully enclosed cabin and the undercarriage was of fixed tailwheel type.
Made by Homebuilt aircraft.
