Hi Igur, At those radii in 1:32 scale I think it would be wise to increase the spacing. In Templot you can use the dummy vehicle function to check. That's at utils> dummy vehicle spacing-ring menu item. This is 2800mm radius outer, 106mm inner spacing, in P-32: 2_200836_060000000.png Depending on the vehicle dimensions, you can see that running clearance will be minimal. To check: 1. roll the dummy vehicle 2. make a copy of it. 3. make the control on the other track. 4. roll the dummy vehicle on that track past the copied one on the first track.
