Tamiya 18103 - 1/32 Jr Cross Spear 01 VZ Chassis Mini 4WD Kit, Collector Friendly  [18103]

Introducing the Tamiya 18103 Jr Cross Spear 01

The Tamiya 18103 Jr Cross Spear 01 is a compact Mini 4WD model designed by Takayuki Yamazaki. It sits on the VZ chassis, which combines low mass with a reinforced structure suitable for spirited track work and display builds.

Exterior look and canopy design

The Cross Spear 01 echoes high performance road styling with a light gray ABS body. Its detachable tinted light smoke ABS canopy allows you to choose between an open cockpit or a closed-top configuration, improving visual options and airflow characteristics.

VZ platform and structure

The VZ chassis uses a truss connection joining the central section to the lateral cowlings, maintaining stiffness while keeping weight down. Its fixed 3.5:1 gear ratio is aimed at providing a reliable balance between speed and torque for standard Mini 4WD tracks.

Modifications and racing advice

To enhance on-track performance, you can upgrade to a stronger Type 130 motor or swap tyre compounds to suit different surfaces. The inclusion of POM 620 low-friction plastic bearings helps reduce rolling resistance for steadier laps.

Construction and user notes

The kit is largely snap-fit for straightforward assembly, and the driver figure can be removed for custom detailing. Two AA batteries are required to operate the model and are not supplied with the kit.

The Tamiya 18103 Jr Cross Spear 01 is a compact, adaptable Mini 4WD kit offering straightforward builds and sensible upgrade routes for enthusiasts and collectors.
