KitHelix™ N scale, 2 track, 14.5"/2.80%, 16.5"/2.46%, 2 turns Helix upgrade spiral direction:Clockwise is upgradeThis helix rises 2 9 16" per turn and has a maximum rise of 5 1 8". Available exit points in the top loop of this helix are at the following vertical rises: 1 1 8 turns: 2 7 8", 1 1 4 turns: 3 1 4", 1 3 8 turns: 3 1 2", 1 1 2 turns: 3 7 8", 1 5 8 turns: 4 1 8", 1 3 4 turns: 4 1 2", 1 7 8 turns: 4 3 4", 2 turns: 5 1 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
