I was lucky for the festive season to get a couple of Revoslot cars- Marcos and Supra.
These are my first non Scalextric cars, and as I discussed (dare I say!) on another forum, these cars, even with magnets installed are a little tail happy. The general consensus being, they are designed to perform well on large club tracks, rather than my small 8x4 layout. Of course I could add say a neodymium magnet but that would detract from the point and skill required to get the best performance from these clearly very high performance cars.
