In this graduate thesis shortly is explained termin unmanned aerial vehicle and described their development and use through the history till now. Also it is defined and explained termin multicopter such as the types of it and their application. Theoretically and practically is shown quadcopter with X formation, its use, way of controlling that is communication system, calibration and settings of aerial vehicle with the help of Cleanflight platform and the equipment that is needed for image display from the aerial vehicle at the real time i.e. FPV or so called video pilot. Except that individually in short are described all main and additional components of aerial vehicle, types of them, their characteristics and use. When all of the described components are put together in one whole we get an unmanned aerial vehicle that is quadcopter with very good flight characteristics and interesting possibilities.
