My Fly classics are still some of my favorite slot cars. They make for some good, close racing on my track and the type and style and period of cars they represent are one of my favorites (along with Can Am). I have well over one hundred of these little gems. Never had much issue with any of them except for the occasional cracked wheel hub, a rare few whose tires leach oil, and a few popped drive shafts on the front-motored cars. All problems that are easily and inexpensively solved.
