KitHelix™ N scale, 1 track, 17.5"/2.70%, 2 turns Helix upgrade spiral direction:CounterClockwise is upgradeThis helix rises 3 " per turn and has a maximum rise of 6". Available exit points in the top loop of this helix are at the following vertical rises: 1 1 8 turns: 3 3 8", 1 1 4 turns: 3 3 4", 1 3 8 turns: 4 1 8", 1 1 2 turns: 4 1 2", 1 5 8 turns: 4 7 8", 1 3 4 turns: 5 1 4", 1 7 8 turns: 5 5 8", 2 turns: 6 " Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate. Precision cut

Available exit points in the top loop of this helix are at the following vertical rises: 5 1/8 turns: 13 7/8"

Available exit points in the top loop of this helix are at the following vertical rises: 7 1/8 turns: 19 1/4"

1 7/8 turns: 6 3/8"

This helix rises 2 7/8" per turn and has a maximum rise of 11 1/2"

Helix tiles are designed to only connect in one orientation which simplifies helix construction
