and you would have needed to buy the 5T anyway so you can work out what upgrade parts to make for it , and i dunno i saw the video of that guy testing it out on the hpi site and if no one told me it was a 2wd i would have guesed it was a 4WD the way it handled ill give it that , pretty good , the 5b never would have handled like that , the back end would have been drifting all over the place
