Ok, This could be my problem.
At the moment I have a Mamba maxx 57000 and controler running on a 8000mah 3s Lipo.
I have it over geared a fair bit. Standard gearing is 24Tpinion and 54T spur. The setup that i have now is 33T pinion and 54T Spur.

All this is in a traxxas Jato.

So from what you are saying is that with this setup The motor is working too hard and heating up the controler?
I should be looking for a larger motor like a Lehner 1930,1940 or a Neu motor?

Is this correct?
