I've also seen some new decals from C&R that look awesome. They, too, should be available in the Rad! Store soon.
Also, there's a guy out here on the west coast that's making HO scale F-1 cars by hand. They're exquisite works of art that actually perform very well. We're getting ready to make a launch video for them and put the up for sale.
Very exciting times here in the slot car world. What's your favorite new slot car thing?
