The Zlin 22 Junak was a 1940s two-seat cabin monoplane, developed from the Zlin 381 (a licence-built Bücker Bü 181).

Development

Although based on the Zlin 381, the Junak had side-by-side seating for two. It was a low-wing cantilever monoplane with a conventional tailwheel landing gear. It was powered by a nose-mounted 75 hp (56 kW) Praga D engine, although the prototype had a 57 hp (43 kW) Persy III engine. A three-seat variant, the Zlin 22M, was developed and two prototypes of a three/four-seat tourer variant, the Zlin 122, were built.
