Tail rotor for a multicopter

Abstract

The design protection claim relates only to the two large propellers (tail rotor), positioned, at the rear, at the upper ends of the multicopter; these propellers have flat blades not having the classic curved shape, but rather an angular one; the central rotor around which the blades rotate is small; the parts shown in dotted lines are depicted only for better illustration purposes and do not form part of the protection claim.
