My Williams is great with mag on a Ninco track but terrible on wood. But my Minardi is excellent on both. Can you believe I picked up a brand new Minardi with a bashed up body (broken mirror and cracked tail scoop) for about $20. I swopped the bodies and now race with the bashed up one and the new one is put away for one day when I retire the car it can look brand new again. A bit of useless information.
