MC1 (presumably Micro Caster 1) is a line of Hot Wheels wheel types. This wheel was first used on the Tricar X8. Three of them are found on the base of the Batcopter. This wheel is used when a very small wheel is necessary. Mostly used on the Poison Arrow, XT-3, Snow Ride, Tread Air, Solar Eagle III, Wild Thing, GM Lean Machine and Morgan Super 3 among other vehicles.
