A flying vehicle in accordance to an embodiment of the present invention includes a main propeller and a propeller control mechanism for flying the vehicle. The main propeller includes a central base that permits the propeller control mechanism to be connected to the drive shaft. The propeller control mechanism includes a propeller hub and a lower hub with offset knobs that are connected by a link. A returning spring is sandwiched between the hubs and tends to return the hubs to the offset position when a change in a driving torque of the drive shaft causes them to move. The spring and link work in concert to change the pitch and height of the propeller blades while substantially unchanging the tip path plane of the propeller blades.

1. A rotating flying vehicle comprising: a hub having an outer perimeter;an outer ring having a diameter greater than said outer perimeter defined by the hub;a plurality of hub blades extending outwardly and downwardly connecting the hub to the outer ring;a main propeller has a pair of propeller blades extending outwardly from a central base section, a propeller control mechanism is secured to the central base section and is connected to a drive shaft extending from the hub, wherein the main propeller extends from the drive shaft beneath said plurality of hub blades, the main propeller when spinning will cause the vehicle to sufficiently rotate such that the vehicle will fly;a system for determining a directional point of reference for the main propeller when the vehicle is rotating; andthe propeller control mechanism using a cyclic driving torque to fly the vehicle in a specified direction relative to a remote user, the propeller control mechanism includes a link connecting an edge of the central base to a lower section of the propeller control mechanism, and wherein the edge of the central base is in an offset position from the lower section of the propeller control mechanism, the lower section of the propeller control mechanism is further rotatably engaged to the central base, and the propeller control mechanism further includes a spring positioned to return the lower section of the propeller control mechanism to its offset position, wherein a change in a driving torque of the propeller control mechanism causes the link and spring to change the pitch of the propeller blades. 2. The vehicle of claim 1, wherein: central base section of the main propeller has upper and lower edges and includes a plate positioned between the upper and lower edges, the plate has an opening there-through and channeled indentations positioned on either side of the opening on an upper surface of the plate, the central base further includes an arm extending externally therefrom and a first knob positioned on the arm, andthe propeller control mechanism includes a propeller hub having an upper shaft, the upper shaft extending through the opening of the plate and sized to receive the drive shaft therethrough, the upper shaft includes a pair of pins extending outwardly and positioned in the channeled indentation on the plate, the upper shaft further includes a first L shaped member extending outwardly and away from the central base, the propeller hub also includes an annual ring positioned about the extension of the first L shaped member;a lower hub having an annual ring with an opening to receive and rotatably secure to the drive shaft such that the lower hub may rotate independently from the upper hub, extending outwardly from the annual ring towards the central base is a second L shaped member, when assembled the two L shaped members rest against each other such that a free edge of the second L shaped member is positioned against an inside corner edge of the first L shaped member, further extending from the annual ring is an arm with a second knob secured thereto, wherein the second knob is positioned at an offset angle from the first knob;a link having a pair of diametrically opposed aperture ends separately secures about the first and second knobs;a returning spring is sandwiched between the two annual rings, the spring includes ends which extend on either side of the L shaped member; anda locking plate is secured to the plate on the central base, the locking plate includes an opening to receive the upper shaft and includes a pair of cured arms to extend over the pins, thereby securing the propeller hub in position and permitting the pins to pivot in the channeled indentations.
