I agree with Domejuddv10. The Cartrix is superior on the track to the Maserati and Vanwall without magnets. I suspect that most of the difference lies in weight displacement, since the scaleys motors are in the front and the Cartrix's is in the rear, and tire width. The Scaley's are certainly smoother, quieter, better detailed, basically just more refined, but that doesn't take away the appeal for me for the Cartrix because it certainly looks nice. With some well placed weight and a little tire tweaking, I bet these three would make great running partners. I just hope they keep them coming.
