The Żak (old-fashioned "student") was designed in the Lotnicze Warsztaty Doświadczalne (LWD, Aviation Experimental Workshops) in Łódź, directed by Tadeusz Sołtyk in 1946, as one of the first Polish post-war aircraft.

It was powered by the Czechoslovak 65 hp straight engine Walter Mikron III and carried markings SP-AAC.

The design appeared successful and the Ministry of Communication ordered a series of 10 aircraft.

Since it showed unsuitable for glider towing, and old Polikarpov Po-2 appeared the better plane for this purpose, Żak-4 was not built in series, and the prototype was re-fitted with a closed canopy and used as a touring plane in aero club (markings SP-BAE).

Żak-3 SP-AAX is preserved in the Polish Aviation Museum in Kraków (disassembled as for 2007) Data from Jane's All The World's Aircraft 1953-54 [1]General characteristics Performance
