Scalextric brings the thrill and excitement of motor racing to life in your living room! Scalextric is the ultimate motor racing system for all ages, where miniature cars race against each other on special track, getting their power from a slot in the middle of each lane (you will sometimes hear Scalextric called slot racing). Works with ARC PRO Digital. Scalextric ARC PRO is a revolutionary slot car race set system that allows up to six racers, when adding an extra power supply, with lane changing and users to wirelessly create and manage races with a handheld smart device, such as a smartphone or tablet. Race up to six cars at the same time with Scalextric Digital ARC Pro. Perform realistic overtaking, blocking and braking with just the touch of a button! Compatible with existing Scalextric Track. Upgrade your analog powerbase to ARC Pro and utilize this left handed entrance for pit stops! Scalextric DPR Analog cars can easily be upgraded with Scalextric Digital Chip to race on a digital layout.
