We have just set up an Arc Pro system in our office. We have a custom track which is approx 25m. We connected it all up and had led's on the red and green ports on the arc pro unit. The problem is, only 1 car will run on the track with the red controller. The green controller is registering on the app so when you pull the trigger, the percentage shows 100 %, but the second car doesn't move. So essentially, we have 1 car and 1 controller that is working. Any help would be greatly appreciated.
