Abstract
Toy helicopter with a control unit which can be removed from the body of the helicopter and placed in one of several positions. The helicopter has a rotor blade which is powered by a motor connected to it via compound gears and a rotary driving shaft. The motor is controlled by a removable control unit which is inserted into the helicopter body and which has an activating switch. When the activating switch is pushed, the switch contact is moved into position to complete the circuit with the battery contact and the resulting electricity from the battery travels to the motor. The control unit is a self-contained unit which is connected to the driving mechanism of the helicopter by a wire cord which may be stored in the helicopter's body. The unit can be positioned into the helicopter body in one of three positions including a horizontal position so that the toy can be operated on level surfaces, or a vertical position so that the helicopter can be operated while being hand-held, or it may be completely removed from the helicopter body to operate the toy at a distance.
