ABSTRACT:
A system for controlling the electric motor in a remote, radio controlled device includes a regulator controller which supplies energy from a battery to a receiver at a regulated level, decodes the channel output from the receiver to switch power from the battery to the motor when proper signals come from the receiver, and if the battery voltage goes low it cuts off the motor and keeps it off until the battery voltage rises above a threshold level and a manual reset enable device is actuated.
