Brushless e-maxx - new setup questions

[ozdave]

ok great, so it sounds like i I can work this out up to a point but really need a bit of trial an error with my particular setup inorder to get what im after?

Am i correct in thinking that current draw is what drives up the temp of the ESC? and that at higher revs created by more cells means more current? are there any guidelines that can help me determine ESC temp beforehand?
