Reduce Motor Heat for Longer Sessions

The 3Racing 3RAC-MHS7/BU/V2 extended motor heat sink with fan is aimed at lowering operating temps on typical 540 motors. Its active fan delivers steady airflow across the sink fins to manage heat during prolonged running or heavy throttle use. Lower temperatures mean less wear and steadier output over a race or practice spell.

Why This Upgrade Works

Better Airflow: Integrated fan moves cool air through the fin array to speed up heat dissipation.
Built to Last: Sturdy components and finish are chosen for durability under repeated use.
Quick Installation: Matches standard 540 motor dimensions so it is a quick retrofit for many models.
Clean Styling: The blue coating provides a neat, purposeful look on show cars.

Is the 3Racing 3RAC-MHS7/BU/V2 compatible with brushless 540s?

Yes, it is compatible with standard size 540 brushless and brushed motors, provided the mounting and clearances match your chassis.

Will the fan run from my receiver port?

Many setups power small fans from a spare receiver or ESC header; verify voltage and connector type before connecting to avoid overloads.

Does the heat sink change weight balance?

It adds a small amount of weight to the motor area, so check balance if you are tuning handling for competition, but the effect is usually minor.
