I love these little remote cars! I had one as a child and I remember playing with it all day long until I managed to stop it under my neighbor's car wheel and he backed up the car, running over it. That was the end of my mini-racing days. Funny thing though, I went to the famous Maryland used car fair and besides the normal cars sold there, there was a guy selling these mini cars. I think it's a hobby he picked up a while ago and now he's making a living out of it. If I ever go back I'll make sure to point him to your site. Who knows, maybe you can share ideas.
