In addition to posting products out to customers, we here at Dual Circuits are happy to get "hands on" with slot cars. Whether it is the conversion to Scalextric Digital by the simple addition of a DPR plug, the custom installation of a Scalextric Digital chip into another manufacturer's car, or the pre-build of a kit, these can all be undertaken for a modest charge (free of charge if a DPR chip and DPR-ready car are purchased together).
Digital conversions are tested by 3 or 4 laps of our small oval test circuit to ensure that everything functions correctly as soon as you receive it.
