Remote control helicopters are small flying devices that can be operated from a distance using a handheld transmitter. They come in various sizes and designs, ranging from simple toy models to more advanced versions used for aerial photography or racing. These helicopters typically have a rotor system that allows them to lift off the ground and maneuver in the air. Most remote control helicopters are powered by rechargeable batteries and can be controlled with joysticks that manage their altitude, direction, and speed. Some models are designed for indoor use, while others are built for outdoor flying, making them popular among hobbyists and enthusiasts of all ages.
