Effective motor cooling for 540 class units

The 3Racing Extended Motor Heat Sink with Fan is aimed at reducing thermal stress on 540 motors during prolonged use. It is a sensible upgrade for those seeking steadier performance and longer duty cycles.

Aluminium heatsink plus active fan

Its aluminium body promotes rapid heat transfer while the integrated fan delivers active ventilation across the motor shell. This pairing helps prevent temperature spikes during high load sections.

Universal 540 fit and straightforward install

Made to fit standard 540 dimensions, the heat sink mounts easily to most setups and is suitable for both tarmac and mixed-surface applications. Installation requires only basic hobby tools.

Can I use this on sealed body cars?

Yes, but ensure there is sufficient airflow through the body or run a duct to the fan area to maintain cooling effectiveness inside a sealed shell.

Does the fan run on standard battery voltage?

The fan runs on low voltage typical for small hobby fans; check the supplied fan voltage rating and connect to a suitable 3S/2S regulated supply or a switched output as required.

Will this affect motor balance or performance?

The heat sink mounts externally and does not alter internal motor balance. It helps maintain consistent performance by keeping temperatures within optimal ranges.
