KitHelix™ N scale, 1 track, 20.0"/2.50%, 8 turns radius18-0This 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: 24 ", 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 accurate.

6 7/8 turns: 22 1/2"

5 7/8 turns: 17 3/4"

2 1/2 turns: 7 1/8"

This helix rises 3 5/16" per turn and has a maximum rise of 19 3/4"

5 1/2 turns: 18 "

This ensures cars which conform to NMRA standards run smoothly within the helix
