Whisper is a new concept of a two seats multirotor from France. It has 8 engines and fix pitch rotors and is equipped with an electronic power management system. Safety, performance and maintenance cost reduction are supposed to be the main forces of this concept. A joystick allows to manage it in an intuitive manner: by its simplicity it is easy to fly. The multirotor stays within the flight envelope. In case of a single engine failure you may land safety, but it is also equipped with a parachute as there is no
possibility of autorotation landing. Actually, its autonomy is evaluated at around 30 minutes, but further more performing batteries may increase the autonomy. Future tests will allow to precise the specifications. Noise reduction and electrical engine power of the Whisper make it to an interesting future aircraft.
