Muggy's are awesome. Finally got to running mine this weekend and as usual didn't break anything. I gotta 1515/1Y, 14T pinion, JB Welded center diff, and it wheelies like crazy! I love it. It weighs in at 11.5 lbs, with the Big Joes and 8000mah brick. This was my first try with the Neu and it never got above 130 temps. Just awesome. Now I know why Mike is always sold out of them. Losi diffs are great also. I've never had one go out, or had to shim them, just drop and go play.
Forgot to mention if not a Muggy an LST platform is just as good. Since I've converted mine to BL, I've only lost one wheel nut and bent the bumper mounts. There indestrucible. My emaxx always broke, so I made it my shelf queen.
