Development

edit

First flown in September 1931 the WM-10 was a single-bay two-seat primary training biplane powered by the companies own 75 kW (100 hp) MW Sport I engine.[1] The prototype was later modified to take the more powerful 89 kW (120 hp) MW Sport II engine and an improved landing gear and eight were built as the WM-10a and delivered in 1933. The last aircraft was re-engined with a 97 kW (130 hp) MW Sport III engine and larger fuel tanks and re-designated the WM-13 .

Five more aircraft were built with Siemens-Halske Sh 12 engines as aerobatic trainers for use by combat units as the EM-10. In 1938 all surviving aircraft we re-engined with the Siemens engine and all were known as the WM-10. Three aircraft survived with the military to 1941 when they were retired to be used as glider tugs.[1]
