Minimum Curve Radius for a Kato GS-4

[NE4449]

The other day I was looking over some of the curve radii on the layout that my Dad and I are working on. We are using Kato Unitrack, and one of our yard tracks uses two 9-3/4" pieces to form a 90 degree curve. Meanwhile, I have a Kato GS-4 that I have only run on the mainline, but not in the yard yet. The Kato website states that the GS-4 has a minimum radius of 11", but I have a feeling that that number is the recommended minimum radius. So can the GS-4 operate on 9-3/4" curves safely, or is 11" the absolute minimum? Thanks.

I'm pretty sure that my unitrack loop is 9-3/4" radius, and since I was testing that loco, I would say 'yes'.

Thanks Tom.
