ABSTRACT:
A remote control lighter-than-air toy apparatus has an inflatable container having a predetermined shape, such as the shape of a dirigible, for holding a lighter-than-air gas. A gondola is removably attached to the inflatable container and has a shaft extending therethrough and rotatably supported thereon. A reversible electric motor is attached to each end portion of the shaft passing through the gondola with each electric motor having a propeller attached thereto for rotation upon actuation of the electric motor. Each of the electric motors and propellers are rotatably attached to the shaft. A radio receiver is connected to each of the electric motors with a plurality of conductors. A control box has a radio transmitter therein and a plurality of controls thereon for transmitting to said receiver and remotely controlling each motor separately, so that a lighter than air toy can be remotely controlled with two propellers.
