Refine Your Setup with the Tamiya 42190 Sensored Motor

Serious hobbyists looking for controlled power and repeatable response will find the Tamiya 42190 sensored brushless motor well suited to competition and club use. Its construction supports fine adjustments to match vehicle dynamics.

Octa-Wind Efficiency and Precision Sensor Alignment

The Tamiya 42190 combines an octa winding pattern with a 12.5mm magnet to produce a compact, efficient power band. The precision sensor assembly can be adjusted or swapped to achieve cleaner commutation and better low-speed driveability.

Designed Cooling to Sustain Performance

Front cooling provisions on this motor assist in reducing thermal buildup during extended running. Keeping operating temperature stable helps maintain output and lengthens component life under frequent use.

Adaptable for Road or Off-Road Racing

From tight circuits to rougher surfaces, the Tamiya 42190 suits a range of RC disciplines thanks to its multiple winding choices and kv options. Tuners can adjust gearing and electronics to prioritise acceleration or top end as needed.

Specifications

With serviceable sensors and considered cooling, the Tamiya 42190 helps drivers reach predictable, tunable performance across different race environments.

How do I choose between the different Tamiya 42190 windings?

Pick a lower turn number for higher top speed and a higher turn number for better torque. Consider track layout and battery voltage when selecting a winding for optimal performance.

Does the motor require special ESC settings?

Use an ESC that supports sensored operation and set timing and startup parameters to match the motor s winding and intended use. Fine tuning ESC settings improves throttle feel and efficiency.

What checks should I do after installation?

Verify motor mount alignment, check for any rubbing of cooling covers, confirm sensor wiring is secure, and run a short test at low speed to ensure smooth commutation before full-power runs.

How can I keep temperatures under control during heats?

Use appropriate gearing, monitor motor temps with an infrared probe, and consider additional airflow or short breaks between heats to prevent thermal drop in performance.
