Abstract: A complex regulator of a remote-controlled car or remote-controlled boat includes a power input terminal, a power output terminal, a switch regulator, and a linear regulator. The switch regulator and the linear regulator are both connected between the power input terminal and the power output terminal and regulates the input voltage after which the input voltage is conveyed to the power output terminal. The switch regulator and the linear regulator have different operational conditions. When the remote-controlled car or remote-controlled boat is operated under a heavy load condition and the input voltage is consequently reduced to a level lower than the first threshold voltage and higher than the second threshold voltage, the switch regulator stops regulating the input voltage and the linear regulator continues regulating the input voltage to maintain the operation of the controller of the remote controlled car or boat.

Abstract: The present invention provides an electronic speed controller capable of detecting a battery type, which comprises a circuit board, a speed control module, a first detection socket, and a power socket. The speed control module has a first power management mode and a second power management mode. The first detection socket and the power socket are electrically connected with the speed control module. The former is provided to connect a first connector of a battery and the latter is provided to connect a second connector of the battery. The speed control module detects whether the first detection socket is in conductive status so as to determine the battery being a first type battery or a second type battery. If the battery is determined as the first type battery, the speed control module performs the first power management mode. Otherwise, the speed control module performs the second power management mode.

Abstract: A forward/reverse transmission, shiftable under servo-control, includes a movable clutch bell and a free-wheeling, one-way centrifugal lock-out clutch that permits a gear change from forward to reverse or reverse to forward only while the engine is operating at or below idle speed. The centrifugal lock-out clutch includes a spring-loaded pawl which is yieldably biased by a compression spring and held in a non-interfering, shiftable position when the engine is being operated at or below idle speed. As the engine rpm increases above idle, the centripetal acceleration force overcomes the bias force of the compression spring and the pawl is extended radially outwardly for engagement with a torque transfer pin. In the radially extended position, the pawl is disposed for interference contact against the clutch bell housing, thus preventing clutch engagement/disengagement.
