I got an old R/C car lying around, it should be in good shape as I've kept it indoors and I haven't used it that much. It has a proper engine and all, but I remember having problems with it when I got it because I was a bit too young. Maybe I should try running it again
EDIT: Added image. I had a look at it just now and electronics are still go, responds to the remote like it should. Just need to get the engine started and it should be all good to go.
