The contest was won in August 1939 by Wsiewołod
Jakimiuk. The resulting design was an all-metal, low-wing fighter aircraft, with retractable landing gear and tail wheel. The plane was to be armed with a single 20mm gun firing through the propeller shaft and four 7.9 mm machine guns in the wings.

Hispano-Suiza 12Y would reach 1,100 horsepower (820 kW) of power in two to three years. Such engines would be sufficient to power the PZL.50, or any other similar fighter design considered by the Polish construction bureaus at the time.

Possibly the design would also allow for up to 500 kilograms (1,100 lb) of bombs to be carried under the wings or the fuselage. The projected speed was to exceed 500 kilometres per hour (310 mph). Project prepared in August 1939 was rejected in favour of
