Turbine Helicopter Bell UH-1B Helicopter Information
The Turbine Helicopter Bell UH-1B (HU-1B) came equipped with a more powerful engine, a Lycoming T53-L-5, a longer cabin, and revised main rotor blades. The larger cabin allowed for accommodation of seven passengers. Later models of the 1B used Lycoming T53-L-9 and L-11 engines allowing a higher gross weight. The civil version is the Bell 204B.
