What cooling or maintenance is needed?

Keep airflow around the motor and check bearings periodically. Brushless motors reduce routine maintenance, but regular inspection of connections and cooling is recommended.

Is the supplied pinion included?

Pinions and wiring are not included. You will need to choose a suitable pinion and solder the motor leads or fit compatible connectors for your ESC.

Will battery choice affect performance?

Yes, battery voltage and discharge rate influence RPM and torque. Match the motor to batteries and gearing for the balance of acceleration and top speed you want.
