1. A speed controller, comprising:
- a housing adapted to be mounted in a radio controlled model car having a DC motor, a battery, and a receiver; and
means defining a control circuit for controlling the amount of voltage supplied to the DC motor according to speed information supplied by the receiver, which control circuit is mounted in the housing and adapted to be electrically connected to the DC motor, the battery, and the receiver;
wherein the control circuit includes means for producing an output signal related to the amount of current supplied to the motor and means defining a test point arrangement for facilitating coupling of a separate readout device to the control circuit for purposes of reading the output signal.

Abstract
A speed controller includes a housing adapted to be mounted in a radio controlled model car having a DC motor, a battery, and a receiver, and a control circuit for controlling the amount of votage supplied to the DC motor according to speed information supplied by the receiver. The control circuit is mounted in the housing and it is adapted to be electrically connected to the DC motor, the battery, and the receiver. It includes circuitry for producing an output signal related to the amount of current supplied to the motor and a test point arrangement for facilitating the connection of a separate readout device to the control circuit for purposes of reading the output signal.

13. A speed controller, comprising:
-
a housing adapted to be mounted in a radio controlled model car having a DC motor, a battery, and a receiver; and means defining a control circuit for controlling the amount of voltage supplied to the DC motor according to speed information supplied by the receiver, which control circuit is mounted on the housing and adapted to be electrically connected to the DC motor, the battery, and the receiver; wherein the control circuit includes means for adjustably limiting the amount of current supplied to the motor, the means for adjustably limiting the amount of current supplied to the motor including means for limiting the amount of current supplied to the motor when the amount of current supplied to the motor reaches a selected level and means for adjusting the selected level; and wherein the control circuit is configured to increase the amount of current supplied to the motor at a first rate when the amount of current is less than the selected level and at a second rate that is less than the first rate when the amount of current is greater than the selected level. - View Dependent Claims (14, 15, 16)
