Installation Note

Remove the original ESC fan and install the PowerHobby fan using compatible mounting hardware. Make sure the fan is securely mounted and oriented to direct airflow toward the ESC heatsink.

Keep the fan and wiring away from the motor shaft, pinion gear, spur gear, driveshafts, and other moving components.

Confirm connector polarity before applying power. When using the included 3S adapter, connect it only to a compatible 11.1V 3S LiPo battery. Do not exceed the listed 11.1V maximum operating voltage.
