A remote-controlled aircraft refers to an aircraft that can control flight from a long distance. Most remote-controlled aircraft are sold as all-in-one machines, and the manufacturers have already debugged them. For some beginner models, they have reached the state of ready to fly, and the prices are relatively low.

Toy helicopters come in various sizes and shapes, and their prices also vary depending on brand, function, and material. Some toy helicopters are also equipped with lights, sound, and other special effects to enhance their fun and appeal.
