Century Helicopter Products UH-1B Huey Cobra User manual

The UH-1B Huey has more than earned its place in the annuals of aviation history, its
having become the very symbol of the Vietnam war. As early as 1952 the Army's
equipment development guidelines called for a state of the art helicopter for general
utility missions, Bell was awarded a contract to build and test this model which began
in 1954 with the first flight. Century's UH-1B is a newly designed version of the full-
size Bell UH-1B, manufactured by Bell Helicopters. The fuselage is finished in high
quality epoxy fiberglass with a clear windshield, every little detail improves the ap-
pearance of your UH-1B helicopter. such as additional three-dimensional panels,
hinges and Nowadays many a model is virtually indistinguishable from its "big
brother". Pilots at scale contests prove this again and again.
