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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
