That helps, basically I guessed that the centre diff should not run hotter than the motor, which it was.

I got a Castle Mamba Monster / 2650kv combo thinking I wanted the fasted motor for 4s running. However it was running about 180F on 13/46t gearing (40mph top speed) on grass after 7mins with a twin fan heatsink which is too high. The ESC was above 150F as the fan was on. I have since obtained a Castle 2200kv and changed gearing to 15/48t with a new centre diff running 15000cst. I will do another run in similar conditions and check all temps again.

I suspect if I try running a 6s pack I will need 20,000 or higher.
