Wikipedia defines "Radio-controlled aircraft" in this way: Radio-controlled aircraft is a model aircraft controlled by a remote controller, not a toy (obviously, Radio-controlled aircraft has become a toy nowadays). The control method is usually radio waves, and some remote control systems use infrared, but it is extremely rare. Radio-controlled aircraft is powered by motors or small engines. There are also unpowered remote controlled gliders.
The flight principle of Radio-controlled aircraft is exactly the same as that of real aircraft, so it is very difficult to control. The simple Radio-controlled aircraft sold on the market can only control the motors on both sides of the main wing to adjust the direction, and the operation is relatively simple. But the Radio-controlled aircraft used by real professional enthusiasts is very complicated in all aspects, which can control the elevator, Rudder#Aircraft rudders, aileron, motor or engine, etc. It usually takes some time for beginners to become familiar with how to operate, assemble and maintain Radio-controlled aircraft, and how to use relevant equipment.
