This SE.3000 is a development of the German helicopter Fa.223. Incidentally, Professor Focke himself took part in building the aircraft. Principally designed for transport purposes, this helicopter carried, in addition to the two-man crew, four passengers in a cabin situated behind the pilot's seat. This cabin was forward of the engine compartment. The aircraft was also equipped with a weight-lifting mechanism, which really turned it into a helicrane.
The fuselage was constructed of welded steel tubing. It was fitted with a fin and a rudder. The rotors, the centres of which were 12.5 metres apart, were carried on cantilever outriggers.
