ABSTRACT:
A toy aircraft includes a main body portion having a central hub member and a plurality of wings. Each wing of the plurality of wings is equally spaced about a central axis of rotation. The toy aircraft further includes a power source carried by the aircraft, at least one motorized propulsion unit interconnected with the power source, and at least first and second propeller assemblies interconnected to the at least one motorized propulsion unit. The first and second propeller assemblies each include a plurality of blades arranged for rotation within a substantially horizontal plane. A preferred construction of the propellers includes a propeller shaft and a plurality of blade portions equally spaced about an axis of rotation defined by the propeller shaft. Each blade portion is formed from foamed polystyrene. A preferred construction of a control system for controlling the flight of the toy aircraft includes a handheld remote control unit and a receiver circuit positioned on the toy aircraft.
