Thermal Control for Competitive 540 Applications

The 3Racing 3RAC-MHS004/TI is engineered as a compact thermal management solution for 540 motors used in competition. Titanium construction provides a high stiffness-to-weight ratio and improved thermal conduction for steady temperature control during heats.

High Flow Cooling and Robust Construction

An integrated fan directs air through a dense fin array to reduce thermal peaks and support sustained motor output. The titanium body resists wear and maintains efficient heat transfer across repeated runs and setup changes.

Installation and Tuning Considerations

Fitment targets standard 540 dimensions for easy installation, allowing racers to add thermal margin without major chassis changes. When tuning, evaluate airflow, motor timing, and run length to optimise cooling benefits in race conditions.

By lowering peak temperatures, the assembly helps maintain motor timing stability and consistent power delivery over multiple runs, which aids repeatable lap times.
The unit adds modest mass at the motor location. For precision setups, account for this when finalising balance and suspension tuning.
Verify secure mounting, confirm there is no rotor contact, and run a short test at low speed to confirm there are no vibrations before full-power runs.
