Race-Focused Cooling for 540 Motors

The 3Racing 3RAC-MHS5/BU/V2 is designed with racing applications in mind, directing airflow across the motor can to assist in temperature control during high-load operation. The compact fan profile is sized to align with the 540 motor form factor for straightforward integration into performance builds.

Performance-Oriented Benefits

  • Optimised Airflow: Fan-shaped fins channel air to key motor surfaces to aid heat extraction and promote consistent output under load.
  • Durable Execution: Manufactured to withstand repeated assembly and the demands of trackside adjustments common in race environments.
  • Tactical Fitment: The unit mounts easily to standard 540 motors, allowing quick swaps and minimal setup disruption.
  • Functional Finish: The blue treatment provides a corrosion-resistant surface with a professional race-ready appearance.

Will the heat sink affect motor timing or gearing choices?

It is a thermal accessory and does not alter electrical timing; confirm mechanical clearance with specific pinion sizes to maintain correct gear mesh.

Is this suitable for tuning sessions and baseline testing?

Yes, adding controlled airflow can stabilise motor temperatures during setup runs, helping you compare components with reduced thermal variability.

Any mounting tips for race teams?

Ensure secure seating on the motor can and verify clearance around the pinion and motor mount; quick checks between sessions keep fitment consistent.
