If you take a stock chassis what are the required hop-ups to have a car that is consistent to drive and is reliable. I'm looking to get a dNaNo to practice with at home; I race Z's but my apartment is just way too small to put a Z track up in, but for dNaNo I could have enough room to get a few turns in.
I think bearings are obvious, but otherwise I'm not so sure. I think I'd want the ball diff simply because the feel of driving would probably be better.
