A drone for rescuers was developed in St. Petersburg
The new device keeps stable in turbulence, it can work at an altitudes of up to 6500 meters and get as close to the slope as 100 meters. In comparison, helicopters can not fly above 4,500 meters and get to slopes closer than 900 meters.
The drone has such useful properties thanks to a special X-like fuselage design, like one of a rocket, as well as also an arrangement of wings and a displaced center of gravity, the developers say.
A drone can also save money, since rescue operations using a helicopter are very expensive, up to half a million rubles per flight.
