First off, quit believing the speed numbers they put on the box. Nearly every manufacturer inflates those number as a means of attracting buyers.
Having said that, what are you going to be doing with the truck and what kind of budget are you looking at?
The Revo is a great racer and can be made to be very, very fast. It's also a decent basher, better actually than most people give it credit for.
Honestly, I wouldn't even consider the Maxx next. It's a good truck and all but there are better 2nd choices. The Savage, the LST2, The Aftershock, the XTM are all trucks I'd look at before the T-Maxx. If I were looking now that is.
