E revo w/ 5S 4000 maxamps 15C

I have run my MM's up to 5s before, but its close to the ragged edge. I agree with poster above, the batteries are probably not giving enough to make insane power. I have run a 7XL on 5s that would flip backwards with a center diff, 4s was impressive as well. You need better batteries before diagnosing the problem. What's you're gearing

so, running MM w/ 5S is good? cuz, i ran the hell out of it and it never gets hot, just warm to the touch. so does this mean its ok? Im gonna get some Hyperion 5S 4800 and try it out. it has 20C rating and its cheap. $140 what you think?

If you are ot having issues with the 5s setup stick with it. The electronics will run cooler on higher voltage too. 140 is a decent deal for that lipo.
