It's cool. The S2 (yes, that stands for Sprint 2) is better than the Wheely King (I've had both), so you didn't lose on that one.

If the deal with the JRXS is still in the works, pore over that manual. It will have some great info for the chassis. While the JRXS and Type "R" are two different models, they use many of the same parts, and have many of the same adjustments. I love mine and will never sell, as it's the easiest to adjust, is very fast, can drift, and is the one chassis that has almost no drag in it. My ESC/motor run cool all day.

I think you'll like it, once you see it, and once it's adjusted properly, you may not want to part with yours, either!
