They're pretty decent out of the box for a leaf sprung crawler. Don't expect it to perform like an scx10 though, as they are very different beasts.

Maybe check out the mst cmx or cfx too, similar size and performance to the ecx, but far better support. Can get them for $180 with no body, or $270 with a few different choices, eg.
