This is a demonstration of light rotary wing aircraft that are attached to a ground power supply. The wired power supply makes it possible for the aircraft to stay in the air for an unlimited amount of time. This makes it possible to significantly expand the number of areas where these aircraft can be used and to increase their effectiveness. Examples of situations where such drones can be used include: border and frontline observation posts, video broadcasting of events, to carry mobile radio repeaters to extend the range of communications, to lift up lighting equipment, to act as a construction crane, to provide decorative effects, and to attract attention and publicity.
