Hi Pat, don't have a true HO track but have a carrera GO with two 90º corners and that comes out at 455mm with the powerbase it about 525mm across. Hope you can fix your controller.
That's a real shitter with your controller Pat,but these things are sent to try us buddy. Can't wait to see the HO track up and running mate. Well done for another great video buddy 👍👍👍👍
