I was racing the Scalextric Maserati 250F and Vanwall... what fun cars to race. They slide a little bit and it's very controllable up to a point until the magnet is no longer over the power rails and then the car does a flat spin. It is really fun to try to slide them around just a little bit but not too much. Am I the only one racing these? Nobody else seems to be discsussing these.
