Description
Full model upgrade for the top of the MINI-Z series!
Total balance takes performance to new heights
While retaining elements of the excellent MR-03 layout, the new MR-04EVO2 chassis achieves significant performance improvements with changes to the front suspension and a lower C of G that work in synergy with a sensored brushless motor. Both narrow and wide tread settings are available by changing the lower and upper plates on the front as well as the steering tie rod. Adjustable wheelbase allows chassis setting according to body type.
While camber angle is optimized during cornering with the swing of the current upper arm design, the front suspension uses the new kingpin-integrated knuckle to further improve camber stability. Geometric revision of caster and trail etc. delivers more linear maneuverability. New spec front springs for the MR-04 with different hardness are available as options.
Front knuckle design features integrated kingpin with optimized clearance with the kingpin ball for smoother operation. Ball bearings have been changed to 3mm internal diameter for lower rotational resistance.
All 7 ball bearings are 3mm internal diameter for lower rotational resistance to minimize friction loss.
Lower mounting of the AAA batteries on the chassis realizes a lower center of gravity compared to the MR-03. In combination with the chassis shape, this improves stability through corners as well as enhancing speed and control.
Ball differential included as standard optimizes the rotational differences between left and right rear wheels when turning. Also provides moderate slip action to improve traction when excessive load is applied. Silver clear anodized finish to aluminum parts creates a formidable style to match performance.
The new unit also supports high-speed communication with various high-end transmitters and receivers to realize unprecedented control response. Achieves transmission speeds of 0.99ms with KO units (ADV mode) and 0.9ms with Futaba units (EVO2 mode). *Previously 2.6ms ~ 3.0ms

Frequently Asked Questions
This is a kit that requires assembly and is designed as a performance upgrade chassis, so it's best suited to hobbyists with some RC building experience rather than complete beginners. If you're new to RC, you may want to start with a Ready to Run model first.
The MR-04 EVO2 uses AAA batteries mounted low on the chassis for a lower centre of gravity. For exact charge times, please refer to the manual that comes with your specific battery and charger setup.
This is a chassis kit, so it includes the MR-04 EVO2 chassis with suspension components, motor, differential, and ball bearings. You'll need to source a body, wheels, tyres, batteries, transmitter, and receiver separately—check the product listing or manual for the complete parts list.
At 1/28th scale, the MR-04 EVO2 is a compact mini RC car ideal for smaller indoor and outdoor spaces, shelves, and transport. The adjustable wheelbase means it can be set up to suit different body types, but exact dimensions depend on which body you fit.
The MR-04 EVO2 features improved suspension geometry with an integrated kingpin knuckle, lower centre of gravity from repositioned batteries, optimised caster and trail geometry for smoother handling, and a sensored brushless motor for responsive acceleration. It also supports faster transmitter communication at 0.99ms with compatible units.
