Yes, Atlas sectional Matt. Using a mix of flex track and 10" sectional on the straights, but honestly having a little trouble with the flex track (just lack of experience). Much tougher than I thought adjusting the ties to mate with the ends of the rails.
Phil, 49.5" radius on the CZ track, 45" radius inside of that. Working on two more inner loops - 40.5" radius (on the inside below) and 36" radius - with my son, hopefully will have pictures this weekend.
Here's a couple overhead shots of the CZ cars on 49.5" radius. I think the cars look better on the middle of the curve than they do at the end of the curve. That's why Matt (and others) are always advocating for transition curves.
