Tamiya 18635 JR Blast Arrow Mini 4WD MA Chassis Special Edition  [18635]

Summary of the Tamiya 18635 JR Blast Arrow

The Tamiya 18635 JR Blast Arrow adopts the MA midship aero chassis for a compact, well balanced platform that echoes prototype racing lines. It is aimed at hobbyists who prioritise aerodynamic form and straightforward tuning.

Shell Shape and Aerodynamics

The model uses tough ABS plastic with a delta wing arrangement and enclosed front wheels to reduce drag. A diffuser at the rear and tight wheel arches improve airflow control and contribute to steadier handling on lanes.

Key Points of the MA Chassis

By positioning the motor centrally, the MA chassis helps distribute mass evenly and enhances stability through bends. The single-piece chassis eases maintenance, while mounting points accept mass dampers and other tuning parts for improved control.

Upgrade Potential for Competitive Runs

Owners can explore higher-performance motors, specialist tyres and refined gear sets to match lap demands. The chassis is compatible with many Tamiya upgrade components, making it simple to adjust gearing and traction for specific track types.

Building and Tools

The kit assembles with snap-fit parts and is accessible to newcomers, yet offers scope for advanced tuning. You will need a small Phillips screwdriver and plastic cutters. Metallic transfers and 13mm plastic rollers are included for finishing touches.

The Tamiya 18635 JR Blast Arrow offers a precise platform for tuning and race preparation, combining a race-inspired body with a capable MA chassis.
