Kyosho Mini-Z Racer MR-04EVO2 Chassis Set N-MM2 4100KV 32892

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.

Sensored brushless motor provides more precise speed control compared to sensorless motors. The W-MM chassis is equipped with 8500KV or 5600KV, and the N-MM2 is equipped with 4100KV type.

New Front Suspension

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.

New Front Knuckle

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.

Ball Bearings

All 7 ball bearings are 3mm internal diameter for lower rotational resistance to minimize friction loss.

Scrub Radius

Offset of the kingpin relative to the wheel (scrub) is 1.5mm shorter on one
side compared to the MR-03 for improved responsiveness to driver control inputs and suppression of wheelbase changes during cornering.

New Motor Mount & Damper Base Plate

Features new motor mount design for sensored brushless motors. Chassis height can be adjusted in three stages by changing the axle adjustment spacers to suit specific driving conditions. In addition, revision of the friction damper base plate features points for wiring to be secured with nylon straps.

New MM Motor Case

New MM motor case design realizes an even lower center of gravity.

New MM2 Motor Case

New MM2 motor case for L wheelbase with mid motor mount.

Ball Differential

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.

Mounting Hight of IC TAG

0.5mm step between the bottom of the chassis and the attachment point for the lap time measurement IC tag (sold separately) ensures maximum ground clearance when the IC tag is attached. Allows for more aggressive vehicle height settings.

Low Center of Gravity Layout

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.

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

New potentiometer delivers precision and durability with a completely redesigned steering program to realize the best response and accuracy in the history of the MINI-Z. The more precise steering control program allows various settings using the MR-04’s exclusive I.C.S. software.

Also, two-way communication is possible with the KO unit (TLMY mode), allowing various setting changes to the I.C.S. system to be made from the transmitter.

*When using the RM motor case, the rear screw holes for the L wheelbase on the back of the main chassis are not drilled, so the L wheelbase cannot be used. Also, when using the RM motor case, the included sensor cable is too short to reach, so the R246 silicone sensor cable 100mm ( R246-8580 ) is required.
