I have heard a few times that the 60 inch diameter is what I need for the 2 percent grade. I can't fit that, so I'm thinking now I will make a S shaped 2 percent grade, and that should take care of what I need. Thanks to all who answered.

I'm trying to add a second story to the joint here, 1200 square feet. I'll have a helix. Radius will be 60 inches, 2% grade, and the only hidden track, well sort of hidden anyway, depends on which side of the room your on. It will not be stacked vertical.
