History

Built by Beneš-Mráz at Choceň as part of the Beta series that included the Be-50 Beta-Minor, it was powered by a 120-130 hp Walter Major 4 inverted four-cylinder engine. Despite the power, it suffered from vibration at low engine speeds. The prototype was moved to Slovakia in October 1943.

Variants

Only the single prototype was built; it belongs to the Beta series with the Be-50 Beta-Minor and Be-51, and the later Be-252.

Where you'll see it

After liberation the surviving prototype served briefly as the training aircraft C-25. It was one of few pre-war Beneš-Mráz designs to survive the war.
