BELL 47 G-3B-1 "SOLOY" Start

Lycoming engines with horsepower ranging between 260 and 305 Turbo-HP used to fuel the two-blade-rotor. A Franklin 6V4-200 C 32 boxer motor was installed in earlier G-models. However, there were more advanced models that were equipped with an Allison turbine and later a Rolls Royce. A company named Soloy Aviation in the United States converted these models.
Despite its low weight of 800kg, the Bell 47 is not only easy to handle, but also able to fly safely in case of engine failure. Until 1974, 6,000 models of the American multi-purpose helicopters were manufactured. When the Bell 47 was patented for Italian manufacturer Agusta as well as Westland Aircraft from England and the Japanese company Kawasaki, it became one of the most popular and successful helicopters worldwide.
Today, the Bell 47 is a desired rarity and popular with helicopter pilots, in particular the Soloy version. The Bell 47-Soloy, which is considered the most beautiful model, now has its place in Hangar 7 in Salzburg not far from where it once delivered its famous movie performances.
