I have been using a CRX for a couple years now. Changing some things (like servo reversing) is a little annoying, but overall it works pretty well. I think I'm going to get some grip tape and make a thicker grip. I already have the rubber pads, but it's still not big enough. A larger wheel would help as well. Since my foam grip is basically shot, maybe I'll see what I can come up with for a larger one.
