Welp, it looks like they may start offering parts for this afterall...

For them to release that and not go ahead and produce some extra parts, even if it were a "while supplies last" kind of production, seems pretty stupid.
Wow. I only hope they re-release the original gold pan. It was THE rc car to have back in the 80's. I cut the page out of the Tower Hobbies catalog that had the RC10 on it and had it stuck on the wall by my bed. I remember reading all kinds of info on it and wanted one, but didn't get my first...
