The two-seater sports aircraft Fieseler Fi 6 was also equipped with the powerful Hirth Motor HM.60R, which had already given the Fieseler F 5 R speed and agility.
As a further development of the Fieseler F 5 R, the aircraft featured additional optimizations to the wing shape, resulting in improved flight characteristics and an even more elegant silhouette. A prototype from Fieseler-Werke was registered in the mid-1930s under the factory designation D-EBIX.[1]
