Digital Chip - Retro Fit Location
When retro fitting a Digital chip to a Scalextric car ensure that the chip is positioned as close behind the guide blade as possible. Fitting the sensor chip close to the guide blade ensures the correct distance between guide blade and lane change flipper. Additionally, the sensor should also be placed in the chassis so that it is immediately above the track slot. This is normally on the centre line of the car chassis.
If you are unable to retro-fit a chip to a car yourself, your local Scalextric retailer may offer a digital chipping service.
