KitHelix™ N scale, 2 track, 20.5"/2.60%, 22.5"/2.37%, 6 turns Helix upgrade spiral direction:Clockwise is upgradeThis helix rises 3 3 8" per turn and has a maximum rise of 20 1 8". Available exit points in the top loop of this helix are at the following vertical rises: 5 1 8 turns: 17 1 8", 5 1 4 turns: 17 5 8", 5 3 8 turns: 18 ", 5 1 2 turns: 18 3 8", 5 5 8 turns: 18 7 8", 5 3 4 turns: 19 1 4", 5 7 8 turns: 19 5 8", 6 turns: 20 1 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
