I wonder if anyone can advise me here. I have a permanent 8x4 layout with an arc pro power base. After a while I was noticing jerky motion in the cars and dead spots, so I’ve spent time soldering every piece of track to its neighbour so it’s now not relying on the connections made by the track itself. In digital mode, it now runs superbly and I’m able to trickle the cars around if I want to. However in analogue mode, the controllers are ridiculously sensitive .....1mm of movement sends the cars off the track at pretty much top speed. It’s so bad it’s pretty much impossible to complete a lap without crashing unless you come right off the throttle. Before I did the soldering, everything worked fine. I’m very confused. Any advice ? simon
