Tamiya 19453 Great Magnum R FM-A Chassis Mini 4WD Kit - Fully Cowled Retro Racer  [19453]

Great Magnum R overview and heritage

The Tamiya Great Magnum R draws on the Fully Cowled Mini 4WD lineage and the spirit of the Mini 4WD cartoon "Let's & Go!!". Built on the FM-A chassis, this kit balances show-ready styling with genuine track potential thanks to the FM-A front midship motor layout and aerodynamic bodywork.

How the FM-A chassis improves handling

The FM-A chassis shifts mass forward with its front midship motor placement, helping the model track more stably over rises and dips. The kit includes a front skid bar and four rollers, while the rear roller set uses 8mm thickness to reduce wobble in fast straights and corners.

Tuning, appearance and parts compatibility

Hobbyists will find the black-molded FM-A chassis pairs well with low-friction POM parts and the white-molded body for a clean look. The kit ships with blue and white metallic stickers, fluorescent green A-spoke wheels and black low-profile tyres. It runs on a Type 130 motor with a 3.5:1 gear ratio, and offers room for common Mini 4WD upgrades.
