So recently I got this nitro buggy in a trade. I know (think?) it's an HPI RS-4 I just want to know a few things.
1) is it really an RS-4
2) What kind of body goes on it, and how
3) is their any special procedure to do after I run it? It's already broken in, but is their anything I need to add to the fuel or to the motor it's self?
