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.
