About time for another poll. What's the smallest radius curve on your layout? Hidden or visible, doesn't matter. To make this scale-transparent, the answers are in 1:1 scale, you'll have to do some math. Pick the choice closest to what you use.
Smallest I've currently got is 11" in Nscale, but running on Kato Unitrack on the dining room table lets me make major changes to my "layout" very quickly. When I start building a permanent layout I'd like to go 18" or larger.
The smallest I use is 12" radius on the nTrak Mountain Division, otherwise I use 18" minumum on the oNetrak modules and that will be the minumum on my next layout.
Also, I do have a small 2ft x 4ft operating display layout featuring a winter scene which uses 9 3/4 in radius (My Christmas Layout).
Happy Modeling.
Cheers.
I've got a 11 1/2 radius on my HO layout. Of course I need to tell you that it is for a shay and short logging cars. Since all I use is flex track, I make whatever radius that is dictated by size. Most of mine is 22-25" radius.
