Ah, that sounds about right about the weight/balance issue, and I see that the MGM esc is rather chunky to mount it any place else. All very good news though, I've been waiting an age for someone to design a centre diff/motor mount like that for the gmaxx chassis- I dont like offset motors, doesnt look balanced (even if it is weight wise). I figured the chassis rails would need trimming though, they are just too narrow for a reasonably sized spur to fit between them, so that fine with me.

One question I have on behalf of someone on another forum- what centre diff is that you went with? cheers.
