Abstract: An elongate helicopter body including an orthogonally mounted rotatable and pivotally positionable rotor shaft fixedly mounting a solid, annular, convex blade member defined by a parabolic convex curve and terminating in an annular rim, wherein the rim is aligned generally orthogonal to the rotor shaft. Propulsion is provided by an enclosed CO2 cartridge, or alternatively a propulsion propeller in alignment with the body of the helicopter. Modifications of the instant invention include a lift propeller mounted underlying or overlying the solid blade and is of a generally equal diameter to that defined by the blade.
