Experimental study on dynamic efficiency quad-rotor UAV

In recent years, because of its powerful that quad-rotor UAV maneuverability and stability exhibited in civilian and military aspects of great potential, but because of its endurance and power efficiency, it has become a major factor inhibiting the development of UAV applications. In this paper, the power efficiency of the UAV conducted a series of tests. Mainly for motor efficiency and motor temperature-depth comparison test, flight efficiency by comparing different KV values, different pitch diameters and different voltages, summarize results motor rally efficiency optimum range of different quality and reasonable given load motor parameter selection.
