Cheers thanks for the info. I was a little afraid of getting a lower turned motor because there seems to be a lot of people saying they are prone to running very hot. I understand that they are going to run a little hot being a lesser quality motor and all anyway..
If I have the older mamba max (yet to crack it open and check, but I'm pretty sure it is I bought it the day they released the 6900 motor) are they known to run on 5s ok? If i do the 'stage 1' mods that is..
I am holding out for MMM, but in the meantime I'm wondering if it'll work without frying it :) I read a post of yours (i think) elsewhere stating that most 4s setups wouldn't have a continuous draw over 80A, based on that I'm guessing a 5s1p lipo pack constructed from 4000mah cells (rated to 25C continuous, 30C burst) would give pretty respectable performance? being 5s lipo I guess I'd go for the 9XL - which would give about 34k rpm... and gear it from there (16/38 or 17/38 perhaps?)
I've read a bit on running 5s with the MM but nothing conclusive yet...I guess I should just buy the cells and try it, im pretty confident (and competent hopefully

) at pack building so I could always just pull apart and make a 4s2p or something...hmm just speaking my thoughts now lol, any comments from those more experience appreciated :)
