Heinkel He 64

The Heinkel He 64 was a sports plane designed by the German engineers Siegfried and Walter Günter and produced by Heinkel, built specifically for the touring plane championships of 1933. It was a sleek two-seat, low-wing monoplane of wooden construction with fixed tailskid undercarriage and a single-spar trapezoidal slotted folding wing, claimed to be the first of its kind, whose automatic slots allowed steep climbs and low landing speeds. First flown in 1933, it took the first three places in the 7,363 kilometre Europa Rundflug and the first five places in the top speed trials, and pilot Fritz Morzik finished tied second overall. One He 64C was imported into Britain for flap research and later flew in Rhodesia until as late as 1952. The He 64b had a 110 kilowatt Argus As 8R engine and a top speed of 245 kilometres per hour.
