Development

During the period of 1927-33, Messerschmitt designed a series of six sport planes, the single-seat M.17 and M.19, and the two-seat M.23, M.27 M.31, and finally the M.35.[1] With the exception of the M.23, none sold in large numbers. They were all single-engine low-wing cantilever monoplanes with open cockpits and fixed undercarriage. The M.35 kept the extended fuselage of the M.27 and combined it with an undercarriage of single leg, spatted form.[2]

Two different engines were used. The M35a had a 112 kW (150 hp), seven-cylinder radial Siemens Sh 14a, and the M.35b a 100 kW (135 hp) four-cylinder inline inverted air-cooled Argus As 8b. The former was the shorter and faster of the two. The aircraft first flew in 1933.[2]

Operational history

The aircraft was first shown to the public and potential buyers at the 1934 Aerosalon in Geneva. In that year, Rudolf Hess won the Zugspitz trophy in a M.35. In 1934-1935, Wilhelm Stör won the German Aerobatic Championship in a M.35b, and in 1935 the women's prize was taken by Vera von Bissing in a similar machine.[2]

Despite these successes and strong performances at other venues in the late 1930s, only 15 M.35s were built, 13 registered in Germany, one in Spain[3] and reputedly one in Romania.[4] Though the M.35a was faster, the M.35b was commoner; only two M.35as are definitely identified.
