[edit] Design and development
After the failure of his first design, the Brantly B-1, N.P. Brantly decided to design a simpler and less complicated helicopter for the private buyer. The Brantly B-2 had a single main rotor and an anti-torque tail rotor and first flew on 21 February 1953. This was followed by an improved second prototype that first flew on 14 August 1956. The B-2A was introduced with a modified cabin, and the B-2B had a larger 180hp fuel-injected engine. The B-2B has a three-blade main rotor and an all-metal fuselage, it can be operated with skid, wheel or float landing gear. Unusually, to save room, the engine is fitted vertically in the fuselage behind the cabin.
[edit] Operational history
The basic design remained in production for over 30 years. The United States Army evaluated the B-2 (designated the YHO-3) in 1958, although it was not ordered. An improved larger version with five seats was designated the Brantly 305.
