ABSTRACT:
A remote-controlled toy helicopter comprises a body; a motor in the helicopter, a battery for powering the motor, and a receiver for communicating signals between the motor and a separate remote controller. A main rotor with blades is driven by a rotor shaft and causing a first lift force developed by the main rotor when the helicopter is airborne. A system permits movement of the helicopter on the ground, and these can be wheels. The helicopter travels on a floor or ground surface when the main rotor develops a second degree of lift force. The helicopter includes a system to effect motion in a horizontal dimension thereby to direct the desired direction. 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.
