A multicopter having a back-folding landing gear, according to the present invention, comprises: a body; multiple propeller supports of which one end is coupled to the body to be radially formed in the body; propellers which are formed in the other ends of the propeller supports and generate wind down; and multiple landing gears which are formed in the bottom of the body and allows the backs thereof to be folded when the multicopter takes off. Therefore, the present invention minimizes air resistance when the multicopter flies and improves battery or fuel efficiency by preventing levitation force loss, thereby extending flying time at a high altitude. |
