Knoller C.II – Plane Printer

The Knoller C.II was a reconnaissance aircraft built in Austria-Hungary during World War I for use by the Austro-Hungarian army. It was a conventional biplane design with staggered wings, and seated the pilot and observer in tandem in an open cockpit. Like Knoller’s preceding C.I design, the upper wing was swept back, but not as far as it had been on the earlier aircraft. The structure was wooden throughout, with the wings skinned in fabric and the fuselage in plywood. The interplane struts were made of steel and arranged in a warren truss configuration.

Relatively few Knoller C.II aircraft were issued to front-line units, with almost unanimous criticism of the strength, build quality and flying characteristics. Although all the contracted aircraft were built, many were stored un-assembled, due to the advent of other types with superior performance and flying qualities.
