CG1701 CG Slotcars introduces a competition 3D printer MicroCarbon chassis designed as a replacement for the NSR Mosler Chassis. MicroCarbon is the most advanced 3D material available in slot car racing consisting of Micro-chopped carbon infused nylon. Stiffer and stronger than any 3D material in slotcars today. This chassis will accommodate any motor pod with a Slot.it footprint. The chassis includes two (2) MicroCarbon guides - one standard size and one larger for wood tracks. The MicroCarbon competition chassis is very stiff - and a built up Mosler weighs 1/2 gram more than a built up OEM chassis. The feeling has been described as "solid".
