An RC airplane is a model aircraft controlled remotely by a pilot, typically using a radio transmitter and an onboard receiver. The receiver sends commands to servos and other control systems that adjust the aircraft’s surfaces, while a motor or engine provides thrust.
In cyber security, RC airplanes are relevant as connected hardware: radio links, flight controllers, and other electronics can introduce risks if communications or control systems are poorly protected. In practice, builders and operators should use compatible components, inspect power and control connections, and follow the equipment’s security and safety guidance. As with other remotely controlled devices, a secure, reliable control link helps prevent unintended operation or loss of control.
