Udet U 11 Kondor

[1][2] The U 11 Kondor was an open-cockpit, metal-fuselage, wooden high-wing monoplane powered by four 100 hp (75 kW) Siemens-Halske Sh 12 piston engines in shaft-driven pusher configuration.

[1] It had a crew of three and room for eight passengers with a dangerously close clearance between the pusher propellers and rear passenger door, which caused one fatality.

[1] The aircraft was tested by Harry Rother near Munich, finding a tail-heavy condition which required addition of larger control surfaces.

The cost to develop and produce the prototype was a factor in the collapse of the company, which was then taken over by Bayerische Flugzeugwerke.
