Advice after usage: 

1. The motor is watercooled, please do not make the motor touch with water, it need to be cooled with its cooling tube. 

2. For this kit of the ESC, because the motor is sensorless, suggest to use the default value in the ESC, we have tested the kit before shipment with the default value, do not suggest to modify the values. 

If you have other requirement on motor KV, ESC or other questions, please contact us agnes@maytech.cn
