Frequently Asked Questions (FAQs)

1. Which motor is used in cooling fan?

Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.

2. Does RC heatsink work?

A heatsink is not completely ineffective without thermal paste, it just isn't quite as good, I use one of the 3Racing fans & heatsinks (admittedly with 5v fan instead of the original 7.2v) and it does make a difference. The heatsink also gets hot which proves that heat is being conducted.
