Hello folks, I've just joined so please excuse any rookie errors in my first post. I have a Hockenheim from some time in the 90s with a McLaren v Renault. The set works great. I recently purchased 2 Gt Lightnings and they are very fast in comparison to the original cars. They have much stronger magnets and hold the lanes very well. Too well in fact because I can hold both controllers to the max and the cars don't crash. Incidentally, one car is significantly faster than the other, regardless of lane or controller. Do I need a bigger power supply to race properly?
