I had a RS4 MT that I ran on a SS5800, it was okay and fairly fast, but I never felt secure enough with it to full on bash it. I did put a few hop ups on it though, the woven graphite front chassis brace is mandatory if you're gonna drive it any bit hard.

Oh yeah, I turned mine into a buggy by running Super Nitro wheels with 2.2" buggy tires and a XXX-4 body, but sold it because I didn't feel like working out the bugs it had in the driveline (don't really like belts anyway).
