KitHelix™ N scale, 1 track, 17.0"/2.80%, 8 turns radius18-5This helix rises 3 " per turn and has a maximum rise of 23 7 8". Available exit points in the top loop of this helix are at the following vertical rises: 7 1 8 turns: 21 1 4", 7 1 4 turns: 21 5 8", 7 3 8 turns: 22 ", 7 1 2 turns: 22 3 8", 7 5 8 turns: 22 3 4", 7 3 4 turns: 23 1 8", 7 7 8 turns: 23 1 2", 8 turns: 23 7 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
