KitHelix™ N scale, 2 track, 18.5"/2.70%, 20.5"/2.44%, 4 turns outergrade2-61This helix rises 3 1 8" per turn and has a maximum rise of 12 1 2". Available exit points in the top loop of this helix are at the following vertical rises: 3 1 8 turns: 9 3 4", 3 1 4 turns: 10 1 4", 3 3 8 turns: 10 5 8", 3 1 2 turns: 11 ", 3 5 8 turns: 11 3 8", 3 3 4 turns: 11 3 4", 3 7 8 turns: 12 1 8", 4 turns: 12 1 2" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
