About this product
Experience precision racing at 1/28 scale with the Kyosho Mini-Z Mr04 RWD McLaren 720S GT3 in striking white. This ready to run electric radio controlled car arrives fully assembled and ready for immediate action—simply add batteries and you’re set to race. The advanced MR-04 chassis represents a significant evolution in Mini-Z performance, engineered to deliver responsive handling whether you’re navigating indoor circuits or tackling outdoor tracks. Built by one of the RC hobby UK’s most respected manufacturers, this 1/28 Mini-Z combines factory precision with accessible performance for drivers of all skill levels.
The MR-04 RWD platform brings substantial improvements over its predecessor, featuring a lowered centre of gravity that enhances both cornering grip and straight-line stability. Updated front suspension geometry maintains optimal tyre contact whilst integrated kingpin design in the front knuckles delivers sharper, more controlled steering response. Smooth ball bearing operation throughout minimises friction, whilst the rear coil spring damper absorbs track imperfections effectively. The geared differential ensures balanced cornering, and the chassis supports optional upgrades including gyro units for advanced control. This 1/28 scale RC car ships with the Perfex KT-531P 2.4GHz transmitter, front tread adjustment parts, and multiple pinion gears (6T, 7T, 8T, 9T) to fine-tune performance. The pre-painted McLaren 720S GT3 body captures authentic motorsport styling, making this one of the most visually striking Mini-Z by Kyosho options available. Whether you’re seeking an RTR RC car for casual enjoyment or a competitive platform with extensive customisation potential, this electric RC car delivers outstanding value from a trusted RC hobby UK specialist.
