My buddy has the Nitro Evader ST (I have the Losi XXX-NT). I would guess that his truck, after breakin, does approximately 40-45. With stock everything on both trucks, I have been faster off the line, but he has a higher top speed. The Evader is relatively easy to work on. I found it easier to get the gas tank off with his truck than it is on mine. The parts are easy to find and there seems to be a good amount of hop-ups available.

We do a fair amount of bashing, and his broken parts have been limited to a couple of spur gears, a front arm, and the brake disc got fried! Somehow the brake froze shut during one run and fried it to pieces. This hasn't happened again since cleaning it. The spur gears were a result of a problem he was having keeping the brass nut on the LSN tight. The nut would loosen, and he'd have a WOT run away truck! Interesting to watch from my perspective! not so funny to him!

Overall, I think the evader is a good bashing truck. I don't have any experience with the X-Cellerator...

Hope that helps some...
