KitHelix™ N scale, 1 track, 17.0"/2.50%, 8 turns Helix upgrade spiral direction:Clockwise is upgradeThis helix rises 2 11 16" per turn and has a maximum rise of 21 3 8". Available exit points in the top loop of this helix are at the following vertical rises: 7 1 8 turns: 19 ", 7 1 4 turns: 19 3 8", 7 3 8 turns: 19 3 4", 7 1 2 turns: 20 ", 7 5 8 turns: 20 3 8", 7 3 4 turns: 20 3 4", 7 7 8 turns: 21 ", 8 turns: 21 3 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.

This helix rises 2 9/16" per turn and has a maximum rise of 17 7/8"

6 1/2 turns: 21 1/2"

1 1/2 turns: 4 5/8"

Alternating space block locations (inside and outside of the helix) enables better access to all parts of the track for cleaning and maintenance
