My track is Scalextric ARC PRO and perfectly happy with my choice. Track is slightly narrower then Carrera, track easily taken apart if or when required.
Missive range of cars plus Carrera, Policar cars run on Scalextric analog track plus others without alteration. Compared to Carrera the narrower track
allows for smaller radiuses such as R1 curves and expanding out to R2, R3 and wide R4 curves. I would however suggest The R1 curves should
only be used as a here and there for space or slower speed points for added interest, or have to.
Digital wise the Scalextric ARC PRO system runs on either analog or digital with the flick of a little switch. The digital unit comes with 2 wireless controllers
plus another 4 purchased separately, allowing you to run up to 6 cars at the same time. Additional digital track pieces such as cross overs and pit lanes
can be added when and if you require. Also you are able to set up various race types that allow You to set up say as one being a Grand Prix with
the ability of setting in ie: compulsory pit stops, changes for wet weather conditions, tyre blow outs, driver changes engine problems etc: set independently as wished.
