Input (English): Text:  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 MB4a 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.
