XRAY - Model racing cars

Hey there, Im thinking about doing an XB8 or comparable buggy in a brushless conversion over the the winter.

I read an article in Radio Control Car Action magazine, about a brushless Revo and I was as excited about a brushless buggy, since I saw one on the internet a few weeks ago.

What I need is some solid suggestions on equipment I would need, to make an awesome brushless setup for the dirt track. Not just for bashing, but to take on the nitro guys By that I mean sufficent power, and maximum run time. If I have to get $300 worth of batteries, then so be it.

Motor? ESC? Batteries? Gear ratio's? I havent got alot of electric experience, so Im just trying to get pointed in the right direction so I can slowly start ordering the parts and assemble as I go

Thanks guys.
