Features of VOLOCOPTER

SUPREME SAFETY
Superior design systems in all critical areas assuring the highest degree of reliability.
ESPECIALLY QUIET
A Volocopter 2X within 75 meters distance is as quiet as the smallest helicopter within 500 meters distance.
A REALITY TODAY
World’s first multicopter to be granted a certification for manned flights - as early as 2016. It fulfils stringent German and international safety standards.
SO SIMPLE
More than 100 microprocessors automatically ensure perfect stability and control of the multicopter. Even if the pilot lets go of the joystick, the multicopter will retain its prevailing position fully automatically.
Even better, in areas in which autonomous operations are possible, it can simply fly on its own.
COST EFFECTIVE
Fuel is replaced by economic (and increasingly sustainably generated) electricity. On top of this, requirements for maintenance, repair and overhaul are reduced to a minimum through the avoidance of complex mechanical components.
THE FASCINATION OF ELECTRIC
The Volocopter is the first ever fully electric and manned multicopter with a permit to fly. This means no combustion engine, no fuel and no emissions as a result. Instead, the on-board systems and 18 electric drives are supplied by 9 high capacity batteries.
