A somewhat better picture of the Bachwansky co-axial helicopter.Some info:single-seat helicopterone ….hp Evinrude (liquid cooled) outboard piston enginemain rotor diameter 16ftDETAILS: The SNB 3-75 small co-axial rotor homebuilt helicopter was designed and built by Mr. Stan Bachwansky and mainly intended to obtain date for the projected larger Turbodyne 740 (not built). The SNB 3-75 was built in prototype form only and was completed in 1969, but destroyed in a fire and almost certainly was never test flown. (Possibly ground tests were performed only). The aircraft was powered by one (modified) Evinrude liquid cooled outboard engine.Production: 1 Stan Bachwansky, Arcadia, CA EAA # 19314
