KitHelix™ N scale, 2 track, 17.0"/2.60%, 19.0"/2.33%, 6 turns 8turnThis helix rises 2 3 4" per turn and has a maximum rise of 16 5 8". Available exit points in the top loop of this helix are at the following vertical rises: 5 1 8 turns: 14 1 4", 5 1 4 turns: 14 5 8", 5 3 8 turns: 14 7 8", 5 1 2 turns: 15 1 4", 5 5 8 turns: 15 5 8", 5 3 4 turns: 16 ", 5 7 8 turns: 16 3 8", 6 turns: 16 5 8" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
