The Bucker Bu 131 Jungmann was a German training and aerobatic plane in a biplane, fixed landing gear, mixed construction from the interwar period and World War II. The drive - in the Bu 131 B version - was provided by a single engine Hirth HM 504 with 100 hp. The prototype flight took place in 1934, and in 1935 the machine entered the line. The plane did not have on-board weapons. Initially, Bu 131 was established as a grassroots initiative of aviation plants Bücker-Flugzeugbau GmbH, who wanted to create a machine for the basic training of pilots. The machine was easy to pilot, with great flight characteristics and good reliability. The plane very quickly gained the interest of German aero clubs and the Luftwaffe, quickly becoming one of the most important training aircraft in the German aviation. The license for its production was also quickly sold to many countries, including Czechoslovakia, Japan and Hungary. In the course of serial production in Germany, two versions of this machine were created: Bu 131 A powered by the Hirth HM 60 R engine with a capacity of 80 HP and the main production series (Bu 131 B) powered by the Hirth engine HM 504 with 100 hp. There are also license versions, such as Aero C.4.The De Havilland Tiger Moth is a British mixed training biplane with a fixed undercarriage. The prototype flight took place in 1931.
