Try wherever HPI parts are sold. The EDIT brand is owned by HPI. Here is the EDIT website complete with a list of global distributors. It doesn't look like they've hit US stores yet. I'm not sure if they plan to sell to the US yet either. I might be wrong though, all I did was breeze through their distributors list and I didn't notice anything about the United States anywhere, but check for yourself anyway, just in case.
