Unmanned aerial vehicle (UAVs, also sometimes shortened as BLAH; colloquially sometimes referred to as "drone" or "drone" (from the English. drone — drone)) — aircraft without crew on Board. Created for aerial shooting, monitoring ground objects and other tasks in real time.

Distinguish UAVs for military and civil purposes.

Also they are divided into:

  • automatic (unmanaged directly, deistvuyuschii for a given program);
  • remotely-piloted vehicles (RPV).

UAVs can be divided on such interrelated parameters as mass, time, distance and altitude. There are the following classes of devices:

  • "micro" (code name) — weighing up to 10 kg, the flight time is about 1 hour and a flight altitude of 1 kilometer;
  • "mini" — weight up to 50 kg, a flight time of several hours and up to a height of 3-5 kilometers;
  • medium (MIDI) — up to 1000 kg, time of 10-12 hours and up to a height of 9-10 km;
  • heavy — with altitudes up to 20 kilometers and a flight time of 24 hours or more.

Here you can make and the variety of copters.

In connection with the mass use of this type of radio-controlled models for shooting of celebrations, promotions and other activities should emphasize. The copter is a radio controlled flying platform with 3, 4, 6, 8, 12 brushless engines with propellers. In flight, the platform is in the horizontal position relative to the surface of the earth may hang on a specific place, to move left, right, forward, backward, up and down and rotated around its axis. All actions are performed by changing the thrust on each motor. Currently drones are used extensively for photo and video shooting of objects.

Beyond flying the same copter in the air can rise several devices, which are special programs able to operate synchronously, forming various figures and drawings.

The drones, like other aircraft, can be equipped with LEDs. The LEDs can be different colors and have a large range of glow and scintillation.

Civilian UAV distributed all collected at home.

Aircraft modelling is a kind of technical creativity, one tool of which is the creation and piloting as the expense of building a traditional (gliders, time) and remotely controlled (RC, kordovye) aircraft.

Model airplanes can and are trying to run in the sky of various unusual objects, because even among the store models are very strange looking. However priemuschestvenno the number of modelers prefer to make their own hands, which increases the diversity of forms. Also they can be equipped with LEDs.
