Abstract
The present invention concerns an aircraft having a plurality of lifting and thrust rotors, with an electric motor and an inverter for each motor. In order to provide an aircraft having a greater payload, connecting bars are provided between the motors. In that respect the invention is based on the realization that, if such connecting bars are arranged in the manner of a latticework, they can provide a light but nonetheless stable structure for the aircraft, and that structure can carry correspondingly greater loads.
