Compact Race Chassis Kyosho 32797 MINI-Z MR-03EVO (W-MM/5600KV)  [KY-32797]

MR-03EVO Chassis Overview and Origins

Released in December 2018, the Kyosho MR-03EVO changed MINI-Z racing by separating the receiver board from the main chassis. That change lets drivers pick their preferred transmitter and tailor setups for different tracks. High-speed processing and modular construction helped it gain quick acceptance among serious RC racers.

Powertrain Notes for the 5600KV Brushless Motor

This MR-03EVO kit includes the KYOSHO SPEED HOUSE XSPEED 56 brushless motor rated at 5600KV. Housed in a single-piece aluminium casing, the motor benefits from improved heat dispersion under sustained load. Full ball bearings and the Ball Diff Set II are included to reduce drivetrain loss and sharpen balance during acceleration and corner exits.

Modular Setup and Receiver Choices

The chassis design emphasises modular swapping of ESC and receiver components, making transitions between brushed and brushless setups straightforward. Supported receiver types are RA-40, RA-41, RA-42, and RA-43, compatible with many transmitters from makers like Futaba and Flysky. That flexibility suits newcomers stepping up from Readyset cars and racers chasing precise control.

Track-Focused Features for Competitive Use

Small but purposeful updates such as a redesigned receiver cover and an improved front upper arm mount make tread and setup adjustments faster. The lightweight layout combined with the advanced motor lets drivers extract lap time without complex modifications.

For hobbyists focused on tuning and lap consistency, the Kyosho MR-03EVO chassis set balances adaptability with race-ready hardware, making it a sensible choice for both learning drivers and club competitors.
