For the original poster, adding what you want to do with your car will help narrow down recommendations rather than people just shouting out their favorite brands.

For example, if you want to race, you're going to need to look at the Futaba/Airtronics stuff. If you want to go around your yard, the really cheap Chinese stuff may be Ok but if you're going near a track, the input lag will prevent you from ever becoming truly competitive. If this is for a rock crawler, you will need additional channels and so on.
