i had one during 3 monthes, it seems like a big toy to drive... i never ran a stock e-maxx but i can imagine that they are equal.
I sold my E-zilla back after applying 2x7cells + a carbon chassis. I have a good racer e-maxx, therefore it looked like a turtle for me... Stock tranny will not handle BL power...

What you have to know about this 10th scale MT, is that it's hard to find some replacement parts. There are no interesting upgrade at the moment for this truck also. After trying both i prefer my Maxx... so much things to do with this kind of chassis.
