KitHelix™ N scale, 1 track, 18.0"/2.40%, 8 turns radius18-0This helix rises 2 11 16" per turn and has a maximum rise of 21 3 4". Available exit points in the top loop of this helix are at the following vertical rises: 7 1 8 turns: 19 3 8", 7 1 4 turns: 19 5 8", 7 3 8 turns: 20 ", 7 1 2 turns: 20 3 8", 7 5 8 turns: 20 3 4", 7 3 4 turns: 21 ", 7 7 8 turns: 21 3 8", 8 turns: 21 3 4" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.
