This electric helicopter invented by a German designer consists of four large horizontal rotors, 16 small propellers and a central drivers seat. It is simple to operate, and its relatively independent component structure allows it to land safely even if one rotor or engine fails. Although this helicopter can only fly for 10 to 30 minutes due to battery capacity constraints, its appearance provides new ideas for the development direction of future aircraft.
Design: Thomas Senkel, Stephan Wolf & Alexander Zosel
