KINGZJ, have you drove the MBX-5???? I can tell you from experience that is the best buggy I have ever driven straight out of the box with the standard kit set-up!!! If you comparing the X5 to the XR is like comparing the MTX-2 to the MTX-3 theres that much difference. The local Kyosho factory driver's only comment was (OH MY GOD thats good, OPPS I carn't say that!!!)
