Race-Grade Control from Tamiya 42158

Built for competitive use, the Tamiya 42158 brushless motor provides steady torque and throttle response for lap consistency. The 12mm rotor keeps the motor compact while delivering usable power across typical racing demands.

Selectable Windings for Track Tuning

Drivers can choose from 6.5T through 9.5T windings to fine-tune RPM and KV to suit track surfaces and race style. Each winding alters the powerband so you can set the motor to complement your gearing and tyres.

For Those Comfortable with Advanced Setup

These motors are aimed at experienced hobbyists who can handle soldered connections and careful tuning. They are unsuitable for drift setups and perform best when used with Tamiya Volac Brushless or Volac Brushless BL2 ESC units.

The Tamiya 42158 offers a precision focussed option for racers who prioritise controllable torque and efficiency. Proper installation and matching ESCs are essential to get the intended performance.

Higher T windings give stronger low-end torque, which helps out of slower corners. Try 8.5T or 9.5T for tighter layouts.
Use good quality solder and heat-shrink, keep joints clean, and avoid overheating the windings. Secure wiring to prevent movement under load.
On long runs or hot days, extra airflow or heat-sinking improves reliability. Keep the motor ventilated to maintain peak efficiency.
It is recommended to use Tamiya Volac Brushless or Volac Brushless BL2 ESCs for full compatibility, though other quality brushless ESCs may work if settings are matched carefully.
