software and manual Oxigen digital racing system for Scalextric Sport Digital,Carrera or NINCO N-Digital track and cars . The Oxigen system supplements the existing Scalextric or NINCO systems chips and the lane changers and lap-counting sensors in the track. The advantage the Slot.it Oxigen system offers is that you can use the same car to race on Sport Digital or NINCO N-Digital. The Oxigen system will also allow any of the cars to operate on virtually any analog track using a wireless controller. The Slot.it Oxigen system operates with a 24Ghz Wireless with the option of up 20 cars. Each already digital-equipped car must also be fitted with a Slot.it SCP-1 module. The Slot.it SCP-1 cartridge talks the in-car module, then the in-car module powers the motor and talks to the lap counter.
