Kyosho MINI-Z RWD MR-04 RC car RTR McLaren 720S GT3 No. 03 (Orange)

The Kyosho MINI-Z RWD MR-04 RC car readyset puts the MR-04 chassis, a painted McLaren 720S GT3 body and a Syncro KT-531P radio into a compact package you can drive the moment you install batteries. Ideal for indoor racing or learning the basics of R/C, this readyset combines a low center of gravity chassis with user-friendly controls for precise handling at small scale.

Key Features

• Authentic electric small-scale R/C car you can run indoors, true 1/28 scale handling.
• Readyset package with a fully assembled chassis, finished painted body and radio for fast setup.
• Includes the multi-function Syncro KT-531P transmitter with steering wheel and pistol-grip throttle for familiar control feel.
• MR-04 chassis – the latest evolution from MR-03, designed for a lower center of gravity and sharper handling.
• High-quality pre-painted McLaren 720S GT3 body with applied decals, finished to display standard.
• Compatible with all MINI-Z racer series bodies; front tread parts are included to match non-standard bodies (motor case and diff gear assembly for some bodies required separately).
• Geared differential (gear diff) provides smooth, predictable cornering response.
• Full ball bearing specification reduces rotational drag across all axles.
• Optional gyro unit (MZW711) can be added; gyro sensitivity is adjustable from the chassis volume control.
• Wide range of MINI-Z optional parts available so you can tune and replacement performance over time.
• Factory assembled chassis for consistent setup out of the box.
• Pre-painted body, complete with markings in Papaya Orange to match McLaren race livery.
• 2.4GHz Perfex KT-531P transmitter included for reliable radio link and training-mode speed limiting.
• Front tread adjustment parts set included to change the front track to suit alternate bodies.
• Pinion gears in 6T, 7T, 8T and 9T included for simple gearing changes.
• Spare nuts supplied to keep you running after routine maintenance.
• Wheel wrench and pinion gear tool included for quick wheel and gear service.
• Tires and wheels installed and ready to drive.
• AAA-size alkaline batteries x 4 supplied for the chassis so you can power the car immediately.
• AAA-size alkaline or Ni-MH batteries x 4 can be used for the transmitter; four AAA included for the transmitter.
• McLaren 720S GT3 body in Papaya Orange reflects the car's racing livery and FIA GT3 styling.
• MR-04 improvements: lower center of gravity for better cornering and easier control compared with MR-03.
• Steering control improved by new front knuckles with integrated kingpins, reducing scrub by 1.5mm per side.
• Front suspension geometry dynamically aligns camber with upper arm movement to keep tire contact during turns; revised caster improves steering response.
• Battery placement is lower than MR-03 to improve cornering stability and straight-line handling.
• Rear uses a coil spring damper to cushion impacts and stabilize driving; optional oil-filled shocks are available as upgrades.
• T-bar rear suspension plate mounts the rear pod (motor and axle) for effective suspension action; FRP and carbon optional parts are available.
• All axles use low-rotation-resistance ball bearings and the same bearing size front and rear for parts commonality.
• Parts set included to change front tread to match non-standard bodies; rear tread changes by swapping wheel offset.
• Syncro KT-531P transmitter provides trims, dual-rate steering adjustment and a training-mode default for reduced speed control.
