Overview of the Spin-Axe Mk.II

The Tamiya Spin-Axe Mk.II stands out in the Mini 4WD range thanks to its compact silhouette and practical build. Inspired by rally machines, it offers a balance of looks and track-ready durability for hobbyists.

Shell Design and Styling

The model shows distinctive oblong light clusters and aerodynamic bodywork that suggest quick handling. The shell is manufactured from tough ABS resin to withstand contact typical in tight races.

Details of the MS Chassis

The Spin-Axe Mk.II uses the MS Chassis, a three-part platform noted for its stable behaviour and serviceability. It supports double shaft motors and makes power delivery predictable on short, technical layouts.

Performance Tuning Options

The kit is aimed at tuners, with room for a variety of upgrades. Options include faster motors, low-profile tyres, and precision gear sets like the Mini 4WD Pro Super Speed Gear Set to tweak acceleration and top speed.

Build Notes and Power Requirements

Assembly is largely snap-fit, streamlining construction and repairs. The body is compatible with other Mini 4WD Pro chassis types, and the model needs two R6/AA/UM3 batteries, which must be purchased separately.
