Rumpler C.VI
The Rumpler C.VI was a high-altitude reconnaissance aircraft used by the Germans during the First World War. The aircraft was designed, along with the C.VII, based on the previous success of high-altitude Zeppelins, from which the engine was also taken: the Maybach Mb.IVa high-altitude high-compression engine. In order to operate in the thinner atmosphere, the aircraft also had a special carburetor and a radiator; however, the radiator was half-sized in order to reduce weight.
