About the MR-04 Mini-Z

Advanced Chassis with Optimized Handling

The MR-04 chassis is a notable evolution from the MR-03, featuring a lower center of gravity for improved cornering stability and straight-line control. It incorporates a revised front suspension with updated knuckles and caster angle for more linear steering and precise response. A geared differential and full ball bearings come standard, reducing drag and enhancing cornering performance. The chassis also supports future upgrades like a gyro or oil-filled rear damper to elevate control and smoothness on various surfaces.

User-Friendly Radio System and Adjustability

Paired with the Syncro KT-531P transmitter, the Readyset provides intuitive control for drivers of all skill levels. It includes key tuning functions such as trim adjustments, steering dual rate, and a training mode for reduced speed operation. The transmitter’s ergonomic design replicates the feel of real car controls, making it both approachable for beginners and satisfying for seasoned RC enthusiasts. With support for different gear ratios and tread adjustments, the system allows for customization as the driver's skills progress.

Scalable Platform for Future Upgrades

While the MR-04 delivers a complete driving experience out of the box, it’s also fully compatible with a wide range of Mini-Z Racer bodies and performance parts. Whether users are looking to swap out the shell for another scale model or enhance handling with optional FRP or carbon parts, the chassis supports long-term tuning and customization. It’s a platform built to evolve with the driver, offering both a solid foundation for beginners and the flexibility to meet more advanced performance demands.
