'''Radio control''' (often abbreviated to '''RC''') is the use of [[control signal]]s transmitted by [[radio]] to [[remotely operate]] a device. Examples of simple radio control systems are [[garage door opener]]s and [[keyless entry system]]s for vehicles, in which a small handheld radio transmitter unlocks or opens doors.  Radio control is also used for control of [[model vehicles]] from a hand-held [[radio transmitter]]. [[Industrial organization|Industrial]], [[Military organization|military]], and [[scientific research]] organizations make use of radio-controlled vehicles as well.  A rapidly growing application is control of [[unmanned aerial vehicle]]s (UAVs or drones) for both civilian and military uses, although these have more sophisticated control systems than traditional applications.
