16D/Super 16D Motors

16D and Super 16D motors are the basic "entry-level" motors for all slot racing (a Super 16D is basically a balanced version of a 16D). While initial costs are low, quality varies widely, and domestic replacement armatures are becoming increasingly popular. For drag racing purposes, power output ranges from very low to low. An extremely popular choice for Bracket and Index racing, several heads-up Classes also utilize these motors.


C-Can type motor

"C-Can" Motors

C-can motors are the most prevalent and popular in slot car drag racing. They range from Group 10 (using armatures such as Wasp, Hornet, Contender) to Group 12 and Group 20 (both using a different specified wire gauge and number of armature winds). While Bracket & Index racing permit any motors, a vast majority of Classes specify a G12 or G20 motor. All Class Racing G12s use bushings, while most (but not all) G20s use ball bearings.


Cobalt "Cobalt" Motors

Cobalt motors, named after a primary component of their magnet material, are usually referred to as "Group 7" or "Open" motors if the armature is unrestricted, or "Group 27" motors if so specified. They commonly use a frame or "strap" for their support structure, and most frequently use ball bearings. Because of the powerful nature of cobalt magnets, G7 & G27 motors are extremely small and compact.
