But is this new e-maxx is better than the revo?? That's what i want to know. Because if YES, i'll switch for this new one.
Tis is a single speed or two speed?
And the metal top and idler, this is a good hardened steel?

But, the best of all will be to drop in an 1/8 scale bugg center diff in this stock revo frame. But i think it's not possible, because if it was possible, i'am sure that a guys here would did it.
