KitHelix™ N scale, 2 track, 19.5"/2.20%, 21.5"/2.00%, 4 turns innergrade2-20This helix rises 2 11 16" per turn and has a maximum rise of 10 3 4". Available exit points in the top loop of this helix are at the following vertical rises: 3 1 8 turns: 8 3 8", 3 1 4 turns: 8 3 4", 3 3 8 turns: 9 1 8", 3 1 2 turns: 9 3 8", 3 5 8 turns: 9 3 4", 3 3 4 turns: 10 1 8", 3 7 8 turns: 10 1 2", 4 turns: 10 3 4" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
