Design and Development

Designed to meet a requirement for an air observation post and army co-operation aircraft the Si 201 first flew in 1938. Evaluated against the Fieseler Fi 156 and Messerschmitt Bf 163.[1] The Fi 156 was ordered into production and only the two prototype 201s were built.

The Si 201 was a high-wing braced monoplane with a tail-wheel landing gear. Powered by a Argus As 10C mounted above the wing and driving a pusher propeller.[1] It had a boxy, fully glazed forward fuselage with room for a pilot and observer in tandem.
