Another Brushless Revo Project

I was able to route the wiring for the fan to the receiver. No problem there. Its a 5-7.4v novak fan and I have the CC BEC set to 6v.

I got the 4s 8000mah lipo today from true rc. I cant wait to see that it can do tomorrow.

Do you think the MM and 7xl can handle a 4s lipo?

I have noticed that most are running 8xl's in there revo's or emaxx's. Whats the advantage of a 8xl over a 7xl? I have been looking for an feigao 8xl but cant find one anywhere. Im not looking to spend the money for a Neu but im looking for another motor. I noticed that the rc monster store has wanderer's on stock.......is the wanderer 8xl comparable to the fiegao??
