Introduced in December 2018, the Kyosho MR-03EVO refreshed the MINI-Z range by relocating the receiver board off the main chassis. That design choice makes it simpler to adopt a preferred transmitter and to reconfigure electronics for different driving styles. Fast internal processing and a serviceable modular layout helped it find favour with track-focused pilots.
This chassis is supplied with the KYOSHO SPEED HOUSE XSPEED 56 brushless motor rated at 5600KV. The motor sits in a single-piece aluminium housing to aid heat dispersion. The set also includes full ball bearings and the Ball Diff Set II to cut rotational drag and improve stability through corners.
The split ESC and receiver approach allows easy moves between brushed and brushless configurations. Compatible receiver units listed are RA-40, RA-41, RA-42, and RA-43, which support a wide selection of transmitters such as Futaba and Flysky. That compatibility path makes it accessible to newcomers and useful for racers refining their setup.
Small refinements like the updated receiver cover and a revised front upper arm mount make tread adjustments quicker at the track. Its light overall mass and efficient motor package deliver the kind of responsiveness needed for competitive MINI-Z racing.
The Kyosho MR-03EVO chassis set is a compact, tuneable platform that works well for those wanting a straightforward upgrade path into refined MINI-Z racing.
