A radio-controlled (RC) model vehicle system is provided including a transmitter and an RC model vehicle containing a receiver. The transmitter includes a transmitter binary large object (BLOB) parameter profile and a transmitter BLOB Version. The receiver is wirelessly, communicably coupled with the transmitter and includes a receiver BLOB parameter profile comprising RC model vehicle parameters corresponding to the RC model vehicle, and a receiver BLOB Version. Changes to the transmitter BLOB are saved to the transmitter and increment the transmitter BLOB Version by one. The transmitter is linked and bound to the receiver, and the receiver BLOB Version is compared to the transmitter BLOB Version. When the RC model vehicle is motionless and the receiver BLOB Version is less than the transmitter BLOB Version, the receiver BLOB is updated with the transmitter BLOB and the receiver BLOB Version is updated to the transmitter BLOB Version.

A model car has a car chassis having at least three wheels, a steerable wheel and a steering gear, a spring mechanism that stores energy used to steer the steerable wheel, and a coupling/decoupling mechanism arranged between the spring mechanism and the steering gear. The steering gear has an input gear wheel connected to the spring mechanism, an output gear wheel connected to the steerable wheel, and two intermediate gear wheel paths each comprising an intermediate gear wheel providing an connection between the input and output gear wheels on alternative intermediate gear wheel paths, and the input gear wheel is movable by the coupling/decoupling mechanism to mesh with at least two of the intermediate gear wheels.

A radio-controlled (RC) motorcycle is disclosed with a chassis, a rear wheel, and a steerable front wheel assembly. The motorcycle includes an attitude estimator that uses rotation and acceleration data from an IMU to estimate an inertial attitude of the motorcycle. A receiver is connected to a control processor and receives a steering input from an RC transmitter. The control processor determines a desired roll angle based at least in part on the steering input from the receiver; determines a reported roll angle from the attitude estimate; and controls a steering angle of the front wheel assembly to reduce the difference (or reduce error) between the desired roll angle and the reported roll angle.
