Hi rawk crawler.
Glad to hear you got your money back. it's sad but true that the quality of rc toys are terrible. maybe they think kids are gentile with them. IDK. it's like they make them to be used once then have you buy another because they don't have replacement parts and if they do you will pay way to much for a crappy china part. the electronics can be fixed but with crappy parts once you burn one thing out other components are going to be compromised from a short or heat.
Most of the time those are around 1:12 scale. i have had a few of the toy rc's and next to my 1:10 scale rc's and they are a bit smaller so i would say they are 1:12 scale or at least close to that.
