#radio controlled

• Model aircraft — A small-scale aircraft built as a miniature replica of a real plane or based on an original design, capable or incapable of flight, used for sporting, recreational, educational, or experimental purposes. Flight-capable model aircraft can be radio-controlled, control-line operated, or free-flying, and are built from lightweight materials such as balsa wood, polystyrene, or carbon fiber.
• Aeromodelling — A practical sporting-technical activity or hobby consisting of designing, building, tuning, and flying model aircraft. As an official sporting discipline governed by the World Air Sports Federation (FAI), aeromodelling includes national and international competitions organized across various aircraft classes (free flight, control-line, radio-controlled, or scale replicas).
• Scale model car — A small-scale model of an automobile, equipped or not with a functional engine (electric or internal combustion) and a radio control system, used for recreational, competitive, or educational purposes. In automotive design engineering, the term also defines the small-scale experimental prototype used in wind tunnels to test drag and fluid dynamics before mass production.
