The MR-03 chassis heralds a new era in the world of the
Mini-Z Racer. The objective first, was to develop a chassis that could provide better
handling dynamics than the older MR-02 chassis and this peak performance chassis
doesn't disappoint. It blows its predecessor away! Second, the chassis
needed to be versatile so, that all the previous
MR-015 and MR-02 series bodies would fit. This allows almost all of the bodies from all previous Mini Z racers to fit
The MR-03 chassis is uncompromisingly designed for racing
performance. It is considerably narrower than the MR-02's predecessor and has a
much lower center of gravity. This results in significantly higher cornering
speeds and very agile handling. The newly developed chassis front wheel
alignment gives the maximum mechanical grip and perfect traction in all driving
The Mini-Z MR-03-Racers are equipped with the latest 2.4
GHz wireless technology. When you turn on the transmitter the entire frequency
band is automatically scanned and selects a free channel. This eliminates
the need to organize finding frequencies for drivers. A total of up to 40 models
can be operated simultaneously with this new system and there are no crystals!
The frequencies are generated by a PLL synthesizer.
Along with the new 2.4GHz radio technology, all the
electronics have been revised for the MR-03. The new processor runs faster and
in conjunction with the Hi-Speed FETs gives the MR-03 ultra fast response to
user inputs. The MR-03-Racer does not include the 2.4 GHz transmitter. The
Kyosho Perfex KT-18 transmitter No.
KYO82001 is not included with the MR-03 sets and must be purchased separately.
Some of the new hi-tech features are included in the new
electronics in the MR-03. The RA-22 2.4 GHz receiver control unit can use the
optional DNW-107 piezo gyro to increase the stability of the car. The piezo-gyro
detects movement of the vehicle about its vertical axis (skidding), long before
they are visible to the human eye and controls it within a split second.
In the front of the car sits a high-resolution digital
servo, which receives the steering commands and translates them in a split
second to the wheels. The new servo has a coreless servo motor which is durable and fast.
The gear ratio in the servo is 94.41:1.
The front wheels are independently fitted with
spring-mounted, double wishbone suspension. The high-grip, low profile tires
give the MR-03-Racer uncompromising traction. In conjunction with the extremely
low center of gravity a breathtaking driving dynamic is achieved which, on
models of this size has never been realized before. These precision designed
cars drive and
handle more like their much larger counterparts.
The control board of MR-03-Racer comes equipped with an
ICS interface. With a special USB cable and software, purchased separately (KYO82080),
the chassis setup can be programmed by your computer. The setup data of the
vehicle can be conveniently stored on your hard drive.
The rear axle of the MR-03 chassis is based on proven MR-02
components. Through the spring loaded Powerpod, the chassis is very flexible and
adapts to any road situation perfectly. The batteries are mounted so that the
center of gravity is very low for improved
The Unbelievable paint finish
is actually hand polished!
One of the special features of the MR-03 is the amazing
pre-finished body. After assembly
and final quality control, the models are hand polished and brought to a perfect
shine. The detail and
finish is "Show quality" and deserves a place on display under glass.
However, if you decide to run yours in the sun light, the MR-03-racer looks like
a precious jewel!
VCS (Variable Camber Suspension)
– The upper control arms are connected to king-pins and knuckles with ball
links and allow the camber angle to change with suspension stroke, just like a real car. Tire contact with the surface remains constant, even during
chassis roll and suspension stroke from surface tracing. The newly developed
digital steering servo uses a coreless motor that delivers quick steering
response and sharp maneuverability that feels like its riding on rails.
Also, the upper arm and one-piece cantilever provide ideal cushioned
movement for the coil spring. In addition, the stainless steel king pin and
wheel shaft deliver smooth movement for excellent running stability.
Precision geometry settings eliminate toe in and toe out change during
suspension stroke and produce a neutral steering feel. The innovative VCS
(Variable Camber Suspension) represents a significant evolutionary step in
the history of the MINI-Z.
Digital Steering Servo
- The powerful position retention and movement of the digital servo is
enhanced with the adoption of a coreless motor that provides instantaneous
pick up and stopping. In addition, the newly developed steering gear unit
has 3 times the gear ratio of previous versions for greater power in holding
it's position so it keeps it's line firmly in the face of kickbacks from the
road surface and also delivers even more precise movement and response.
- Same battery layout as the MR-02 chassis achieving a low center of gravity
with a main chassis width equal to the narrow MR-015.
Compatible With All ASC Bodies
- The main chassis is compatible with all MINI-Z ASC, AutoScale bodies,
ranging from MR-015, MR-02 and AWD. Pick and choose from any body in the
Mini Z AutoScale body series; there are 100's of bodies to choose from.
*Special motor case and differential gear assembly is required to fit some
RA-22 2.4GHz RX TX Technology
- Equipped with the new next generation RA-22 2.4GHz RC unit specially
designed for the MR-03. Requires no frequency bands. Simply switch power ON
and enjoy safe and stable control. SF 2.4GHz system automatically scans for
open frequencies and promises safer and more secure control.
Coreless Motor + New Gear Reduction Ratio
- Digital steering servo features a coreless motor and a gear unit that has
3 times the gear reduction ratio of previous units for powerful movement and
Adjustable Front Tread
- Can be set to either narrow or wide tread by replacing the front lower and
upper plates and steering tie rod. Of course the wheelbase can still be
adjusted to suit certain car types.
- Coil springs in the front suspension can be easily replaced by removing
the spring stopper with just two screws. Motor mount can be easily removed
and replaced to suit whatever chassis configuration you want to run from a
MM, RM, HM or LM type of mount.
- FET speed control amp with more than double the capacity of previous
version produces extra powerful running performance.
KT-18 2.4GHz Transmitter
- Newly developed 2.4GHz R/C system requires no frequency crystals and
automatically scans for open frequencies, allowing up to 40 cars to be
run together. Simply switch the power on for stable control without
interference. The fastest signal processing in the history of R/C results in
almost instantaneous reaction to the driver's will for a more direct control
feel. By pairing the transmitter to the chassis, a single transmitter can be
registered and used with multiple 2.4GHz MINI-Z models. To match the latest
R/C technology, a new generation LM chassis has been developed for even
greater performance. *Transmitter Sold Separately Item KYO82001
