Abstract: A remote controlled flying toy figure has a thrust-powered, weight shifting rudder head. The flying toy figure comprises a head, a body, a propulsion system, and a control system. The head is attached to the body by a flexible support member, making the head securely fixed in flexible relation to the body, thus permitting a yawing motion of the head relative to the body. The propulsion system comprises two independently operable motorized propellers, each of which is attached to opposite ends of a steering bar. The steering bar and head form an integral steering unit. Increasing the thrust from one of the propellers causes the figure to turn in the opposite direction. This increased thrust causes the steering bar to yaw, which moves the center of gravity of the head to the opposite side of the center line of the body, which causes the figure to bank towards the turn.

Abstract: Provided are flying devices and methods of manufacturing and launching same, in particular flying toys or other recreational items that are designed to be thrown through the air by a user participating in any one of a variety of throwing (i.e. “catch”) games.

While the non-rotating portions alter the airflow associated with a typical flying disc, they do not negatively affect the flight characteristics of the disc itself. Indeed, in certain embodiments, the non-rotating portions (e.g., ailerons) have been observed to improve the flight characteristics of typical flying discs.
