Slot Cars

Ranidart70 you have HO cars & track. It looks like most are Tyco/Mattel which are a lot of fun. I think you should set up a simple track, even an oval is fun, and run some cars. Clean the track rails with a pencil eraser along with the electrical pick-ups on the cars. Clean the track and rear tires on the cars , if really dirty I use lighter fluid. There's a really confusing selection of new and retro cars, each are great but you need to get your stuff running first. Let us know how it goes.

As for the 1/32 stuff that's a whole 'nother topic which can wait for now.
