Hi Mike, Fly just released their GT40 cars, thats why almost none on eBay and the limited production ones first. Then the good user ones will be out for about 40 bucks a pop that we can really race. My Lola handeled terrible till I added an extra magnet, and put silicon tires on it. Most of my flys handle better than any scalextrics that I have owned, The c5 vettes are great, the vipers are awesome(too easy for me , wife and kids like them , because they can sometimes beat me ,,lol) , As matter a fact ,, the Fly C5s are a good match for the scalextric GT as long as you move the magnet , full aft in the GT and add one small round one to the small holder in the front of the car,, well thats my 2 cents worth,,haha regards , Dan /ubbthreads/images/graemlins/smile.gif
