Tamiya 18634 JR Astralster MS Chassis Mini 4WD Kit - Racing Ready  [18634]

Introducing the Tamiya JR Astralster 18634 - compact Mini 4WD racer

The Tamiya JR Astralster, model number 18634, showcases precise Mini 4WD engineering from designer Kota Nezu. This compact kit blends style and practical raceability, making it a popular pick for hobby racers who enjoy tuning and track performance.

Closed-body styling and finish

The Astralster features a closed-type body with a matte surface and mirrored window and lamp details. The understated finish gives it a clean, race-ready look that still reads well on display and on the starting grid.

MS Chassis balance and fit

Its MS Chassis provides a stable, modular platform that accepts a double-shaft motor for efficient power delivery. The chassis layout simplifies assembly and leaves room for common Mini 4WD upgrades and setup tweaks.

Tuning and upgrade options

There are plenty of upgrade routes for speed and handling: higher torque or high-rpm motors, low-friction rollers, tuned gears and specialised tyres can all be fitted. The broad front and rear fenders also allow for body mods and aerodynamic tweaks.

On-track behaviour and setup

Set up with low-profile tires on the included 5-spoke wheels, the Astralster maintains a low centre of gravity for stable cornering on standard Mini 4WD circuits. Adjusting ride height, wheel alignment and weight distribution will help dial in lap consistency.

The Tamiya JR Astralster provides a solid balance of looks and tuneability. Its MS Chassis and upgrade potential make it a strong choice for club racers and miniature circuit builders.
