The invention belongs to the field of recreation tools, and particularly provides a multi-rotor manned craft adopting a helium balloon to overcome part of gravity. The multi-rotor manned craft comprises the helium balloon, a multi-rotor craft body, a manned cabin, a connecting device and a flexible buffer body. The helium balloon is arranged in the center of the multi-rotor craft body, the manned cabin is located under the helium balloon, and the flexible buffer body is pasted to the top end of the upper portion of the helium balloon. The helium balloon, the multi-rotor craft body and the manned cabin are connected together through the connecting device according to the positions. The helium balloon overcomes part of gravity for the multi-rotor craft body, and after people and cargos are carried by the manned craft, the speed of a motor of the craft does not need to be quite high, so that the purposes of maneuverability of the helium balloon and people and weight carrying of the multi-rotor manned craft are effectively achieved.
