RC aircraft are remote-controlled flying models that can be powered by electric motors or internal combustion engines. They come in various sizes and designs, ranging from small gliders to large scale replicas of real airplanes. Enthusiasts often use them for recreational flying, racing, or aerial photography. These aircraft are typically controlled using a handheld transmitter that sends signals to a receiver on the plane. RC aircraft can be built from kits or purchased as ready-to-fly models. They are popular among hobbyists and can be flown in designated areas, such as flying fields or parks, where regulations permit.
