KYOSHO Mini-Z MR04 EVO2 Chassis Set (W-MM) 5600KV -V2 Gyro Unit
No boundaries, no compromises! A
dedicated CPU has been integrated into the gyro unit’s circuit board,
allowing for ultra-precise control. With faster processing speed,
response time is dramatically improved, eliminating the common issue in
older gyros where higher gain would reduce turning performance. This
next-generation gyro unit delivers unmatched stability and takes
cornering precision to a whole new level. 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
New gyro improves cornering performance!
At the end of 2023, the Mini-Z MR-04EVO2 underwent a full model change
after 14 years. Building on the MR-03’s proven layout, the MR-04EVO2
model introduced a sensor-equipped brushless motor, a redesigned front
suspension, and a lower battery position—resulting 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.
