Old Nitro car
I recently acquired an old collection of nitro cars; my two uncles did some serious things with them between 2000 and 2010. Now I have them, but my question is...
I can't find spare parts online for the body, or rather, I have no idea what this "form factor" is called; there are no brand names, only the engine is a Force .18, a Conrad 15SZ and 17SZ and a VX .18, which is what I've found out.
All the engines still work, etc., I'm really happy about that. I would appreciate more professional help, although I did own a Nitro once, but that was 6 years ago, so I don't really know much about them.
