KitHelix™ N scale, 2 track, 18.5"/2.80%, 20.5"/2.53%, 3 turns Helix upgrade spiral direction:Clockwise is upgradeThis helix rises 3 1 4" per turn and has a maximum rise of 9 3 4". Available exit points in the top loop of this helix are at the following vertical rises: 2 1 8 turns: 6 7 8", 2 1 4 turns: 7 3 8", 2 3 8 turns: 7 3 4", 2 1 2 turns: 8 1 8", 2 5 8 turns: 8 1 2", 2 3 4 turns: 9 ", 2 7 8 turns: 9 3 8", 3 turns: 9 3 4" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
