Not other than the BF-2 being a refinement of Henrich Focke's two-seat BF-1 Beija-Flor (Hummingbird).

Hi,

While working at the CTA Focke also developed the BF-1 Beija-flor (hummingbird) two-seater light helicopter from 1954, which made its first flight at São José dos Campos on 22 January 1959. The BF-1 was similar in design to the Cessna CH-1, with a 225 hp Continental E225 engine in the nose and the rotor mast running vertically between the front seats. An open structure tubular steel tail boom carried a pair of tail surfaces and a small tail rotor. The BF-2 was developed from this and first flew on 1 January 1959, and performed an extended flight-testing campaign until it was damaged in an accident. It is thought that further work on the Beija-flor was then abandoned.
