Radio controlled helicopter
From RC Helicopter Wiki
RC helicopters generally consist of a rigid body housing the engine and main rotor assembly, as well as a tail boom with a tail rotor. Stability has to be achieved manually, with most helicopters using a gyroscope (or "gyro" for short) to stabilize the tail. RC helicopters can be powered by a glow engine using a nitro-methane based fuel, gasoline fueled two-stroke engine, rotary turbine, or using an electric motor.
While electric powered helicopters are advantageous due to their quiet power-trains they are limited in duration of flight as compared to a comparable liquid fueled helicopter. However, they are cheaper to run. Cheapest by far to run are the 'gassers' which run a gasoline-oil mixture not unlike a weed-whacker or a small gas powered scooter.
