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: A method for determining an output signal is provided. A radio device identifier associated with a second radio device is stored in a first radio device. One or more configuration parameter settings associated with the second radio device are stored in the first radio device. The first radio device identifies the second radio device based on the radio device identifier. In response to identifying the second radio device, the first radio device automatically determines the configuration parameter settings should be used to determine an output signal based on a user input. The first radio device establishes a radio communications link with the second radio device. The first radio device receives the user input. Based on the configuration parameter settings and the user input, the first radio device determines the output signal. The first radio device transmits the output signal to the second radio device through the radio communications link.

Abstract: In an embodiment, a modular transmit controller is provided. The modular transmit controller has a user interface module including a steering control, a throttle control, and an attachment portion for attachment of an external device module.

Abstract: A method for determining a command for a radio control receiver and transmitting the command is provided. A radio control transmit controller for determining a command for a radio control receiver and transmitting the command is provided. A method for a model vehicle radio control receiver establishing an exclusive link with a model vehicle radio control transmit controller is provided. A model vehicle radio control transmit controller may automatically adopt a particular control configuration depending upon the model vehicle radio control receiver to which it is linked.

Abstract: In an embodiment, a transmit controller compatible with an auxiliary user interface device is provided. The transmit controller has a memory with operational parameters, a control user interface, an auxiliary user interface connector, and a transmit controller processor. The transmit controller processor is configured to transmit the operational parameters to the auxiliary user interface device and modify the operational parameters in accordance with a parameter instruction from the auxiliary user interface device. The transmit controller processor is further configured to receive a control instruction from the control user interface, determine an output signal based on the control instruction and the one or more operational parameters, and transmit the output signal to the model vehicle.

Abstract: A method for a radio control transmit controller communicating with exactly one radio control receiver is provided. Two or more identifiers are stored in a radio control transmit controller. Each identifier is an identifier of a radio control transmit controller. The transmit controller receives a link request from a first radio control receiver. The link request includes an identifier of the first receiver. The transmit controller determines if the identifier of the first receiver is in the two or more identifiers. If the identifier of the first receiver is in the two or more identifiers, the transmit controller transmits a link response to the first receiver.

Abstract: A method for a radio control receiver establishing a link with a radio control transmit controller is provided. Two or more identifiers are stored in a radio control receiver. Each identifier is an identifier of a radio control transmit controller. The receiver receives a first signal from a first transmit controller. The first signal includes at least an identifier of the first transmit controller. The receiver determines if the identifier of the first transmit controller is stored in the plurality of identifiers. If the identifier of the first transmit controller is stored in the plurality of identifiers, the receiver transmits a second signal to the first transmit controller.
