Installation Note

Remove the original ESC fan and install the PowerHobby fan securely over the ESC heatsink. Orient the fan so it directs airflow toward the 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.
