Kyosho Chevrolet MINI-Z RWD MR-04 RTR 1/28 C8 (Chrome/Yellow)

Kyosho MINI-Z RWD puts the MR-04 chassis and Chevrolet Corvette C8.R styling into a compact 1/28 readyset you can drive right out of the box. This MINI-Z RWD Readyset is built for indoor running and for newcomers who want an authentic small-scale R/C experience: the chassis, painted display-quality body and Syncro KT-531P transmitter all arrive factory assembled.

Key Features

• Authentic electric small-scale R/C car designed for indoor driving and tight layouts.
• Readyset package arrives fully assembled: chassis, painted body and transmitter are included for quick use.
• Includes the multi-function Syncro KT-531P transmitter.
• Features the MR-04 chassis, a major evolution from MR-03 that lowers the center of gravity for improved handling.
• High-quality pre-painted body finished to display standard with applied decals for an accurate Corvette C8.R appearance.
• Compatible with all MINI-Z racer series bodies; swapping bodies may require a suitable motor case and differential gear assembly for some options.
• Geared differential (gear diff) provides smooth, predictable cornering behavior.
• Full ball bearing specifications reduce rotational resistance across all axles for efficient drivetrain operation.
• Optional gyro unit can be fitted to make steering easier; gyro sensitivity adjusts via the chassis volume control.
• Wide range of MINI-Z Racer optional parts supported so you can tune handling, gearing and look over time.
• Factory assembled chassis for consistent setup and less initial tinkering.
• Pre-painted, display-quality body complete with factory-applied markings and anniversary graphics.
• 2.4GHz Perfex KT-531P transmitter included for reliable control and training-mode speed limiting.
• Front tread adjustment parts set included to match non-standard bodies when swapping shells.
• Pinion gears supplied: 6T, 7T, 8T and 9T for quick gearing changes.
• Spares and tools in the box: spare nuts, wheel wrench and pinion gear tool for maintenance.
• Tires and wheels mounted and ready for immediate running.
• Includes (4) AAA-size alkaline batteries for the chassis.
• Includes (4) AAA-size alkaline batteries for the transmitter; Ni-MH batteries can be used as an alternative for the transmitter.
• The Corvette C8.R race car inspiration: midship 5.5L V8 race configuration, aerodynamic parts and weight reduction informed the model’s look and livery.
• MR-04 chassis improvements: lower center of gravity and revised steering geometry for sharper, more linear control compared with MR-03.
• Front knuckles with integrated kingpins reduce scrub by 1.5mm per side and use 3mm inner-diameter ball bearings to cut rotational drag.
• Front suspension links dynamically align camber during travel and revised caster improves steering response.
• Batteries are mounted lower in the MR-04 than MR-03 to enhance cornering stability and straight-line control.
• Rear coil-spring damper cushions road impacts; optional oil-filled shocks are available for a smoother feel.
• T-bar rear suspension plate holds the rear pod (motor and axle) and its flex contributes to effective suspension action; FRP and carbon optional parts are available.
• All axles use low-rotational-resistance ball bearings, and front and rear use the same bearing sizes for spare-part efficiency.
