BL setup question

Ok guys I was recommended to this forum by ***RC***. I'm trying to run a BL setup on my emaxx. I've been doing some reading here and with some helpful advice from ***RC***. What do you guys think with running a Feigao 7xl, Mamba Max esc, and a UBEC.:002:

well its exactly what im running,it should be running fast....you are going to use a 4s Lipo right? but from what i hear the motor runs hot compared to the 8xl but mine(when i get all the part) should be fast.

Um I didn't plan on running lipos. Am I going to have to run them???

Alright guys I've been doing alot of reading here. I think I'm going to have to wait with the BL setup. I have alot of other upgrading to do before my emaxx can even handle BL power. Diffs,cvds, and everything else needed to handle uber power. But I do have a nice blue chassis setup on its way lol.
