Abrégé

A radio controlled two wheeled vehicle incorporates a disposition of two motors, a gear system and electronics to provide a balancing and mobility during operation. There is a low center of gravity provided by relatively heavy wheels. The two-wheeled vehicle provides increased balancing at slower speeds between the drive system motors. In the motorbike, and a figurine having movable joints is attachable to the bike and provides for tilting of the bike and steering effects during the bike operation.

Abrégé

A helicopter includes a system to effect motion in a horizontal dimension thereby to direct the desired direction. The rotor blades are driven by a rotor shaft and which is hinge mounted on this rotor shaft, such that the angle between the plane of rotation of the main rotor and the rotor shaft may vary. A control for moving the angle of incidence of at least one blade of the rotor cyclically along at least part of a 360-degree rotation path around the rotor shaft. This causes a variation in a lift force of the blade along at least part of the rotations path. This causes the body to be urged in a relatively horizontal direction from a relative position of rest. The control includes an actuator for engaging with an assembly depending from the rotor, the inter-engagement of the actuator and assembly effecting a change in the angle of incidence of at least the one blade of the rotor. The system includes a rotor, preferably complemented with a stabilizer rotor. There is a control ring attached to the main rotor, and an actuator device connected with the helicopter body structure. The control ring is generally centered around the vertical rotor axis, and moves with the rotor when tilted around the feather axis.

Abrégé

A helicopter has a main rotor (4) with propeller blades and an auxiliary rotor (5) with vanes which are driven by a rotor shaft and which is hinge-mounted to this rotor shaft (8). The angle between the surface of rotation of the main rotor and the rotor shaft may vary. A swinging motion of the auxiliary rotor around on an oscillatory shaft (30) is essentially transverse to the rotor shaft of the main rotor and is directed transversally to the longitudinal axis of the vanes. The main rotor and the auxiliary rotor are connected to each other by a mechanical link. The swinging motions of the auxiliary rotor controls the angle of incidence (A) of at least one of the propeller blades of the main rotor. There are wings from the body and a stabilizer at the tail.
