Abstract: A motor controller receives user input from a receiver and may change the operating mode of the motor controller according to the operating conditions of a model vehicle. In some embodiments, the user manually selects a mode of operation for the motor. In other embodiments, the operating conditions, for example the speed, power output, or other condition, may automatically trigger a transition between a first mode and a second mode of operation of the motor.

Abstract: In an embodiment, a holder mechanism is provided. The holder mechanism has an upper and a lower sliding plate, an upper and a lower lever guide arm, and an upper and a lower spring. The sliding plates have an adjustment lever plate rod slot and one or more fingers. The lever guide arms have a hinge end and a spring end and are hinged to their respective sliding plates at a hinge end. Each spring pulls the spring end of its respective lever guide arm and its respective sliding plate together. An adjustment lever between the sliding plates has an upper and a lower guide rod. Each guide rod is between the respective sliding plate and the respective lever guide arm. An adjustment lever plate rod passes through adjustment lever plate rod slots in the upper and lower sliding plates, and is connected to the adjustment lever.

Abstract: A system and method are provided for low power electronic speed control for a model vehicle. A remote controlled model vehicle system may comprise a motor, a transmitter, a receiver, and an electronic speed control device. The electronic speed control device comprises a user interface and is at least configured to control a magnitude of average power applied to the motor in response to a user input. The electronic speed control device can operate under at least two profiles, wherein a desired profile is selected by the user. In one embodiment, under a first profile the electronic speed control device applies 100% magnitude of average power to the motor in response to maximum forward throttle, and under a second profile the electronic speed control device applies a percentage magnitude of average power lower than 100% and greater than 0% to the motor in response to maximum forward throttle.

Abstract: A powered scale model vehicle having a transmission with a forward gear and a reverse gear. The transmission is shiftable between the forward gear and the reverse gear. The vehicle has a radio control receiver, a sensor and a microcontroller. The receiver is adapted to output a throttle signal and a shift signal to the microcontroller. The sensor is adapted to obtain a vehicle speed measurement. The microcontroller is electrically coupled to the receiver and the sensor. The microcontroller may be adapted to control a timing and execution of a forward/reverse shift on the transmission based on at least the vehicle speed measurement, the throttle signal, and the shift signal, for example.
