New to the CRT.5 have some questions

[Snipin_Willy]

Ok, I ordered an FMA Cellpro 10s so I should be set for a long time for a battery charger.

I ran it some more to get an idea of what the temps were going to be like. The ESC is heating up much faster than I expected. Batteries and motor barely warm to the touch.
Did some searching and found that maybe my center diff fluid is too loose. Running it in about 100 foot stretches the front tires ballooned a lot more than the rears. Not sure what fluid the previous owned used in the center diff so I'll have to go out and get some.

Would a loose center diff cause the ESC to heat faster than the motor?
