RC aircraft, or remote-controlled aircraft, are model airplanes or helicopters that can be operated from a distance using a handheld transmitter. These aircraft come in various sizes and designs, ranging from small toy models to larger, more sophisticated versions used for hobby flying or competitive racing. They are powered by electric motors, gas engines, or even jet engines, depending on the model. Flying RC aircraft requires skill and practice, as pilots must learn to control the aircraft's movements in the air. Many enthusiasts join clubs or communities to share tips, participate in events, and enjoy flying together. Safety is important, and regulations often govern where and how these aircraft can be flown, especially near populated areas or airports.
