Design and development
The five-seater Model 305 helicopter is based on the smaller two-seat Brantly B-2 that was designed by Newby O. Brantly. The helicopter is powered by a Lycoming IVO-540 flat six piston engine.[1] The enlarged cabin has room for five passengers, two side-by-side forward-facing seats and a bench seat at the rear for three passengers.[1] The Model 305 first flew during January 1964 and FAA type approval was received 29 July 1965.[2] 45 were built during the mid 60's by Brantly and Brantly-Hynes produced an improved version in 1985 of which 4 were built. The Brantly 305 suffered from a ground resonance problems.[citation needed] Hynes developed a more powerful and streamline version in 1993, none were produced.[citation needed]
