the 8xl is a 2200 isnt it? and yes using an external bec the mm should run on 14cell you might wanna get a big external cap and a novak 25mm fan to help it out, and like mikey said lipos will make a night and day difference over the 14 cells, youll prollly get a good bit of cogging and stutering under acceleration with the nimh and lipo wont do that.

its a night and day difference just running a mm and 5700 combo in a tiny buggy between nimh and lipo, im sure it will be more noticable in an emaxx.
