Mould King 11013 Double Helix roller coaster | 2,174 parts

This double helix roller coaster features two helical rail tracks.

The first helix is a lifting mechanism using a worm gearbox that can be driven manually with a crank or automatically with a motor, continuously lifting the carriages to the top.

The second spiral is a high-speed descent where the carriages rush down the spiral.

Both spirals are located in the same tower and are shaped like a DNA molecule!

The lifting mechanism is more reliable and compact, and the entire structure is built on just two basic platforms
