Hi, I have build a new track with ARC Pro (C8435) an have some trouble with it. Maybe you will have a good hint for me. When I have a digital car calibrated once I can't correct it then. Is there a way to handle that?I need a speed limitation for the cars. Is there a way to do that? I need that for digital and analog cars.Is there a way to save the configuration of the Scalectric ARC software?
