At the end of 2023, the Mini-Z MR-04EVO2 underwent a full model change after 14 years. Building on the MR-03s proven layout, the MR-04EVO2 model introduced a sensor-equipped brushless motor, a redesigned front suspension, and a lower battery positionresulting in a major performance leap. Now, the MR-04EVO2 receives a key update with even further upgrades. Featuring reinforced 2.0 front suspension arms previously introduced in the RWD series, the updated model now includes the widely adopted gyro unit set as standard. Upgraded to Version 2, the gyro offers a refined balance of stability and cornering precision, enhancing both race performance and the driving experience. Another key improvement is the new RC unit that enables motor RPM control for precise tuning which is essential for racers while maintaining fair competition as Mini-Z Cup rules shift from regulating motor KV (RPM per volt) to directly regulating RPM in 2025. The MR-04EVO2 fully supports this new system, and with the I. C. S. Setting Manager, users can easily configure motor settings to match class regulations.
