Kyosho makes the Mini-Z RWD MR-04 readyset MAZDA SAVANNA RX-7 (SA22C) "1979 DAYTONA CAR No.77". It is built on the Mini-Z RWD / MR-04 platform. The Mini-Z car in the box is a 1979 Mazda Savanna RX-7 MR-04, and its chassis is factory assembled.
As a Readyset package, it gives the full experience of high-performance R/C car racing right out of the box. It is an authentic small-scale R/C car that can be driven indoors. The easier control of the MR-04 makes it an ideal introduction to R/C cars.
The No. 7 car won the GTU class at the 1979 Daytona 24 Hours. No. 77 then finished 2nd, securing Mazda's remarkable 1-2 debut. The No. 77 Mazda Savanna RX-7 Mini-Z has sharp body lines highlighted by bold red stripes. The red stands in striking contrast to the green of the No. 7 car.
The body is hard plastic, high-quality painted with decals applied and finished to display model standard. The pre-painted body is complete with markings.
The latest high-performance MR-04 chassis is now the standard Mini-Z RWD model. This readyset has the same standard MR-04 chassis as other high-end MR-04 models. A renewed RWD chassis sits at its core. Previous Readyset packages used the 3rd generation MR-03 chassis. The new RWD Readyset has the 4th generation MR-04 chassis, first released in 2023.
The MR-04 chassis is a major evolution from the previous MR-03 model. It retains the best aspects of the MR-03. In the top-of-the-line EVO2 debut model, the MR-04 showed a lower center of gravity and remodeled steering design. The MR-04 showed blistering speed and excellent handling there, keeping some basic elements of the MR-03 design. The lower center of gravity of the new MR-04 delivers significant performance improvements. The batteries are mounted lower than in the MR-03, which lowers the center of gravity of the entire chassis. Cornering stability and straight-line handling are improved as a result.
The MR-04 chassis is mounted with the R/C system. A geared differential delivers smooth cornering. It uses a user-friendly 130-class brushed motor. Power is electric, and the drive type is forward/brake/reverse.
The car has a new front suspension (No. MZ719) that is compatible with zero-offset wheels. New front knuckles with integrated kingpins reduce scrub by 1.5 mm on each side compared to the MR-03. Control becomes sharper and more linear. The change to 3 mm inner diameter ball bearings also reduces rotational resistance.
The front suspension dynamically aligns camber angle with upper arm movement, keeping optimal tire contact during cornering. A revised caster angle improves steering response.
The rear suspension uses a single coil spring damper to cushion shocks from the road surface and improve driving stability. It can be upgraded to an optional oil-filled shock absorber. The T-bar rear suspension plate holds the entire rear pod, including the motor and rear axle. Its flexibility produces excellent suspension effect. Optional T-bar rear suspension plates are also available in FRP and carbon.
All axles are equipped with low rotational resistance ball bearings as standard, a full ball bearing specification. The same size ball bearings are used front and rear for spare parts efficiency.
For a non-standard body, the front tread (vehicle width) can be changed to match it. The rear tread can be changed by changing the wheel offset.
The R/C system is the ultra reliable, multi-function Syncro KT-531P transmitter. The transmitter has a steering wheel that mimics the steering wheel of a real car. It also has a pistol-grip throttle (speed control).
The neutral position of steering and throttle can be adjusted with trims, and dual rate adjustment sets the steering angle. The transmitter can operate in training mode with a reduced vehicle speed, and training mode is the default setting. The car is equipped with a speed control, a receiver and servos.
The car can be fitted with an optional gyro unit for even easier control. Gyro sensitivity is adjusted using the volume on the chassis. A wide range of compatible Mini-Z Racer optional parts lets you tune it up for elite-level performance.
The car is specified as follows:
The box also contains:
The car needs four AAA-size alkaline or rechargeable nickel-metal hydride batteries, and they are not included. The transmitter needs four more of the same type, also not included. The charger is sold separately.
The chassis is compatible with all bodies for the Mini-Z racer series. A motor case and a differential gear assembly suitable for the body are required separately.
