Questions You May Ask:  

• Can I put the ESC underwater directly? Is it ok to work in sea water?

     --Yes, the ESC is with waterproof case, you can put underwater directly, it can use work in sea water, but because sea water has corrosion, to expand the ESC lifespan, please use fresh water to clean the sea water on the surface, and put the ESC for all dry for next time use. 

• I don't want to put the ESC underwater directly, what should I do?

    --If you don't want to put the ESC underwater, don't worry, it's also watercooled, you just need to connect a water pump to cooling the ESC, and if so, please order the kit with 2 sets water pump, each motor pump can only cool for 1 item, in this kit the motor is watercooled also needs water pump for cooling.
