KitHelix™ N scale, 1 track, 20.0"/2.30%, 6 turns Helix upgrade spiral direction:Clockwise is upgradeThis helix rises 2 7 8" per turn and has a maximum rise of 17 3 8". Available exit points in the top loop of this helix are at the following vertical rises: 5 1 8 turns: 14 7 8", 5 1 4 turns: 15 1 8", 5 3 8 turns: 15 1 2", 5 1 2 turns: 15 7 8", 5 5 8 turns: 16 1 4", 5 3 4 turns: 16 5 8", 5 7 8 turns: 17 ", 6 turns: 17 3 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
