To consolidate the success of the Be.50, the Benes-Mraz company developed a modernized version of the aircraft—the Be.51. The main difference of the new aircraft was the enclosed cockpit. Additionally, the Be.51 Beta Minor featured a slightly reduced wingspan.
Initial Design and Production
The lightweight Be.51 sport aircraft was built shortly before the outbreak of the war. The first prototype took to the air in October 1936, and serial production began the following year. It was then supplied to private flying clubs. A total of 65 units of the aircraft were manufactured.
Wartime Service and Luftwaffe Use
By 1939, most of these aircraft were located in Slovakia and were incorporated into its Air Force, with 25 machines being used. The aircraft proved successful, and after the annexation of Czechoslovakia, the German Luftwaffe utilized a large number of these planes for liaison and training purposes.
