About the MR-04

Advanced MR-04 Chassis for Improved Handling

The MR-04 chassis introduces multiple upgrades over its MR-03 predecessor, including a lower center of gravity and improved steering geometry. These enhancements provide sharper, more predictable handling and better cornering stability, essential for on-road racing. The W-MM (wide, mid-motor) configuration also gives users greater tuning potential, making it easier to optimize performance for different track layouts.

Ready for Customization

Ideal for drivers who want to create a one-of-a-kind Mini-Z, this set is fully compatible with Kyosho’s extensive range of Auto Scale Collection bodies and unpainted white kits. You can paint your body to match a real car or your own racing colors. This level of customization makes it perfect for both casual racers and competitive drivers who demand a personalized RC experience.

Reliable KT-531P Transmitter and Balanced Motor Power

Included in the set is the KT-531P pistol-grip transmitter, a user-friendly and reliable controller that makes the Mini-Z feel like a full-sized race car. The 130-class MZ9PB motor delivers balanced power suitable for both beginners and experienced racers. With a wide array of available Mini-Z option parts, you can continue upgrading the performance as your skills progress.
