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.
Made by Knoller.
