The X-5 is very good and solid design as it's based off the very proven and very successful XX-4 Worlds Edition. They won a national championship with it a few years ago. I was able to win a series of races with it in Region 5 that ranged from a very loose and bumpy blown out track to a very grooved and high bite track. The X-5 swept the 3 day, 3 track event with TQ, fast lap, and win at each track. I've not ran it in a few years because electric racing as been about non existent in the area but I'm gearing back up the electrics for bit of traveling this winter and it's the car I'm going to use.
