Designed by Jarosław Janowski in 1967 and built with the help of some friends, it flew three years later.
It had 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.
Original prototype was flown with Saturn engine design by Mr Janowski.
There were several articles in worldwide press in regards of this design and many successfully built all around the world.
