It's an HPI Crawler King. It's really not that fast on straight pavement but that thing sure can climb! It's 4 wheel all the time, and has pretty low gearing.
Used to play around with them a bit had a couple of tmax's and a hpi savage. Wife still has a matrix 1/8 scale buggy and a mugen seki 1/8 scale buggy. Me I fly the rc helis and planes been flying for over 40 years now.
Great hobby to get into.
