Knoller C.II

History:
Knoller C.II is a two-seater multipurpose biplane with a mixed structure: a fuselage made of plywood, wooden wings covered with canvas with a steel internal frame, and the front and upper part of the fuselage covered with sheet metal. The plane had an unusual arrangement of 20 struts connecting the fuselage with the wings. It was powered by a 6-cylinder Austro-Daimler water-cooled engine with a radiator located above the engine.
The plane was constructed by professor R. Knoller from the Technical University of Vienna. In February 1916, during a test flight, the wings of the plane folded and the entire crew died as a result of this accident. All orders to date for this aircraft have been canceled and the two completed ones have been stored and never put into service. In 1998, the only surviving plane was restored and now stands in a museum in Prague.
