RWD series is a Rear-Wheel Drive design that emphasizes superior handling paired with the Syncro KT-531P Transmitter. With just 8 x AAA-size batteries, the MINI-Z Racer allows anyone to enjoy the beautiful style and advanced performance of R/C cars. First launched in 2013, Kyosho has renewed the MINI-Z Racer Sports MR-03 concept to be even more user-friendly and appealing to more drivers with the MINI-Z RWD series! Widely popular body styles in highly detailed body sets create the incredibly realistic model lineup. Including the latest Syncro KT-531P transmitter with steering trim, throttle trim, dual rate, LED control function, the sponge grip of the steering wheel provides comfortable fit for precision control feel. The set also includes a car body finished to display-model standard that matches stunning style with the performance, reliability and durability of the MR-03 chassis. The control program on the new circuit board produces linear handling characteristics and can be further enhanced for even easier control by installing the optional gyro unit (MZW446).
