Heinkel He 64
# Heinkel He 64

The Heinkel He 64 was a sports plane built in Germany in 1933 to participate in the touring plane championships that year, designed by Siegfried and Walter Günter.

## Development

The He 64 was a sleek, low-wing monoplane of conventional configuration with fixed, tailskid undercarriage. The pilot and passenger sat in tandem under a streamlined canopy. Six examples were entered in the championships, which represented almost every example of the type built, the only exception being the first prototype, which had crashed.

## Operational history

The He 64s shone in speed-related trials, taking the first three places in the 7,363 km (4,601 mi) Europa Rundflug ("Rally over Europe"), and the first five places in top speed trials. They also had high positions in minimal speed trial. Although no He 64 had won in any of the other categories, these wins were sufficient to gain pilot Fritz Morzik an overall tied second place in the contest.

One He 64C was imported into the United Kingdom in 1933 for flap research, at first with Handley Page then with the Royal Aircraft Establishment until 1935. This aircraft later flew in Rhodesia until 1952.

## Variants

### He 64a

    The prototype of the He 64 family.

### He 64b

    Initial production version

### He 64c

    Later production offering a variety of powerplants, including the de Havilland Gipsy III, Hirth HM 504A-2 and Hirth HM 506

### He 64d

    Two examples of a high speed version were built, powered by the standard Argus As 8R but with elliptical planform wings similar to those fitted to the He 70 and no Handley Page slats. The maximum speed was increased to 290 km/h (180 mph).
