which esc to buy
 

Ok guys I dont know alot about brushless systems, I have owned an rc18mt with a brushless setup and I also have a quark 33 in my comp rig, but when it comes to making alot of power and dealing with lipos I have no idea.

So this weekend I bought a revo roller and a feigao 8xl inrunner with a 5mm shaft, my plan is to make an e-revo, my question is do I buy a mamba max or should I buy a velineon esc? how do the two compare?

I would also like a couple tips on lipos, I want to run a 4 or 5s lipo, when I go to buy a charger do I buy one that balances or can I get away with buying a duratrax ice?

thanks in advance
