KitHelix™ N scale, 2 track, 13.5"/3.00%, 15.5"/2.61%, 8 turns 7turnThis helix rises 2 9 16" per turn and has a maximum rise of 20 3 8". Available exit points in the top loop of this helix are at the following vertical rises: 7 1 8 turns: 18 1 8", 7 1 4 turns: 18 1 2", 7 3 8 turns: 18 3 4", 7 1 2 turns: 19 1 8", 7 5 8 turns: 19 3 8", 7 3 4 turns: 19 3 4", 7 7 8 turns: 20 ", 8 turns: 20 3 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more
