KitHelix™ N scale, 1 track, 19.0"/2.60%, 3 turns junction

KitHelix™ N scale, 1 track, 19.0"/2.60%, 3 turns junctionThis helix rises 3 1 8" per turn and has a maximum rise of 9 1 4". Available exit points in the top loop of this helix are at the following vertical rises: 2 1 8 turns: 6 5 8", 2 1 4 turns: 7 ", 2 3 8 turns: 7 3 8", 2 1 2 turns: 7 3 4", 2 5 8 turns: 8 1 8", 2 3 4 turns: 8 1 2", 2 7 8 turns: 8 7 8", 3 turns: 9 1 4" Our Design: Our construction system uses alignment jigs (included in your kit), making the build faster, easier and more accurate.

6 1/2 turns: 20 1/4"

2 7/8 turns: 8 5/8"

4 1/4 turns: 11 7/8"

8 1/4 turns: 21 3/8"

4 5/8 turns: 13 3/8"

7 7/8 turns: 20 1/2"

This helix rises 3 9/16" per turn and has a maximum rise of 14 1/4"

5 7/8 turns: 16 7/8"

6 1/4 turns: 21 1/8"

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

6 turns: 18 1/8"
