buggy motor. starting over fresh.

[MBX5's]

hey man....this is a great deal of help, you have no idea how green I am to this stuff. but giv me a V-Spec in a Hyper 8.5 Pro and I can chew it up good.
Now what about the voltage thing we spoke of, what am I looking for, are we reffering to the battery? What kind of 4s/5000 are we talking about? And what would you recommend for an ESC, I seem to read alot about the MMM(MambaMonsterMax I think) and guys having trouble.
