Abstract

A flight platform, comprising a rotor rotating about a rotor shaft for providing the platform with an active driving force, and a flight control system that controls the flight based on measured flight parameters that are measured by sensors, wherein at least one of the sensors is located substantially along the axis of rotation of the rotor.
