Hummingbird II - American multi-UAV, developed by «Reference Technologies».

Unmanned aerial Hummingbird II model tool is intended for use purely in the civil sphere, in this case, the device today is positioned as a research drone used for cartographic, geodetic, topographic and geological reconnaissance, environmental monitoring, patrol and observation flights and so on.

This unmanned aerial vehicle is made in a rather interesting configuration, in particular, the device has a cylindrical shape with a motor located in the central part providing the lifting power to this drone, and along the perimeter of the aircraft there are six additional engines providing maneuverability for the device. The aircraft itself has rather compact dimensions, however, due to its special flight-technical characteristics, a large amount of equipment is used to control it, which in turn causes some difficulties with mobility.

Its first flight this aircraft means produced in 2015 year, and due to the fact that the tests have been successfully completed, the project was sent to a limited production, with constraints related mainly to the fairly low demand, and as of early 2017 years, for all time produced only 8 drones this model.

Power means of this air is represented by seven electric motors operating on gasoline electrical generator which in turn provides the ability to filter a rate of about 60 km \ h when the device is in autonomous air to 6 hours.
