KitHelix™ N scale, 2 track, 19.0"/2.50%, 21.0"/2.26%, 5 turns outergrade2-72This helix rises 3 " per turn and has a maximum rise of 14 7 8". Available exit points in the top loop of this helix are at the following vertical rises: 4 1 8 turns: 12 1 4", 4 1 4 turns: 12 5 8", 4 3 8 turns: 13 ", 4 1 2 turns: 13 3 8", 4 5 8 turns: 13 3 4", 4 3 4 turns: 14 1 8", 4 7 8 turns: 14 1 2", 5 turns: 14 7 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
