Siebel Si 202

The Siebel Si 202 Hummel was a civilian sporting and training aircraft of the Siebel Flugzeugwerke.

History

The aircraft was developed in 1938 by Friedrich Fecher on behalf of Siebel to spread the flight sport in Germany. The aircraft was therefore designed as easy to flying, robust, cantilever low- wing monoplane of wooden construction. The chassis was designed as a rigid standard suspension. The first flight of D- ESFH took place on 26 April 1938 Wolfgang Ziese as a pilot. By the time quite advanced design and through the adjacent pilot seats with dual control in a closed cabin, the aircraft was popular. As a price around 6000 Reichsmarks were provided. Since the first Zündapp engines were slow to place, were the V1, V2 and V4 with Salmonella engines that V3 equipped with a Walter - micron in-line engine. Until the outbreak of war three variants were produced, with up to cease production in May 1941 instead of the planned 200 units, only 38 were built. The machines were used mainly in the schools of NSFK.
