Hello all, We have just updated our large (12M) home layout from an old analogue powerbase to an Arc Air and we are now having a lot of problems. The track is maintained in excellent condition, as are the braids on the cars. We have a lot of cars and many different makes, all of which used to run fine on the old power base. Now it is a very differnt story unfortunately. All cars run fine when using the Arc Air power base only, without the app turned on. But oncem the app is on, the trouble begins. Not all of the cars will run at all, and some will run in fits and starts all over the track, and this is with all brands, Scalextric, Ninco, Pioneer, FlySLot etc. It gets even worse if you try to run two cars at the same time, even with two reasonably low-drawing Scaextric cars. Then is we try any of the race apps, it's completely useless. If we do have two cars that run fine, we are lucky to get tow laps in before the app stops due to powercase overload. And this is after sometimes over an hour of free practice runs without the app turned on and without any isses. We have not been bale to have one race with the app, which is defeating the whole purpose of buying the thing. Can anyone offer any advice as to what mifght be causing this issue? I was wondering if I need to upgrade the power supply?
