The Mini-Z RWD series combines a rear-wheel drive chassis that prioritizes driving with the Syncro KT-531P transmitter. The MINI-Z Racer has become a well-established R/C model that anyone can easily start with just eight AAA batteries. The MINI-Z Racer Sports MR-03 Readyset, which was released in 2013, has been renewed with the concept of "making it easier for a wider range of users to enjoy!" It has been reborn as part of the MINI-Z RWD series, which includes a newly developed transmitter and a body with a realistic scale reproduction of a popular car model. The big topic is the adoption of the Syncro KT-531P transmitter. In addition to steering trim and throttle trim, it is equipped with dual rate and LED control functions, and a sponge is standard on the steering wheel to emphasize.
