Helicopter Engineering

Helicopter Engineering

Another French pioneer, Etienne Oehmichen, began his experiments in 1920 by suspending a balloon above a twin-rotor rc helicopter simulation to provide additional lift. A later design had four lifting airscrews and five auxiliary propellers. On April 14, 1924, he flew this type of craft, powered by a 180-horsepower (134-kilowatt) Rhone engine, 1,181 feet (360 meters), establishing the first rc helicopter games distance record officially recognized by the Federation Aeronautique Internationale.
