KitHelix™ N scale, 2 track, 18.5"/2.70%, 20.5"/2.44%, 8 turns outergrade2-66This helix rises 3 1 8" per turn and has a maximum rise of 25 1 8". Available exit points in the top loop of this helix are at the following vertical rises: 7 1 8 turns: 22 3 8", 7 1 4 turns: 22 3 4", 7 3 8 turns: 23 1 8", 7 1 2 turns: 23 1 2", 7 5 8 turns: 23 7 8", 7 3 4 turns: 24 3 8", 7 7 8 turns: 24 3 4", 8 turns: 25 1 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more

2 1/2 turns: 9 1/4"

This ensures the tallest modern cars (autoracks and double stacks) run smoothly within the helix
