<br /> <br /> I’m working on my dream layout. But it requires a helix and some grades. What is a good rule of thumb for an average grade in G scale. As in how much rise per foot is expectable? I have been working with a ¼ “ per foot. Looks good on paper, but -- .. Here is what I’m looking at. I have a 25’ run of track. 25’ x 12” = 300” total inches. A grade of 1/8” or .125 x 300” = 37.5” of rise over the 300” or 37 and ½ “ of rise over 25’ of run. Any ideas ? [?]
