3Racing 3RAC-MHS4/LB/V2 Light Blue 540 Motor Cooling Fan  [3RAC-MHS4/LB/V2]

Targeted cooling for 540 motors

This light blue 3Racing 3RAC-MHS4/LB/V2 cooling unit helps control motor temperature on 540-class setups so performance stays consistent over longer driving periods. It is a simple addition for reducing thermal stress during extended use.

Forced airflow and heat sink design

The built-in fan forces air over a machined heat sink to move heat away from the motor casing quickly. That airflow combined with fin geometry reduces the chance of thermal cutbacks and helps preserve motor output under load.

Balanced weight and durability

Constructed to be lightweight yet sturdy, the cooling assembly keeps added mass to a minimum while resisting regular bashing and running. The pale blue finish gives a neat visual touch without compromising fitment in most rigs.
