I also forgot: The cars need lap bars like seen in the images on this page.

I mean, how else is the "harness" function of NoLimits 2 supposed to work with this coaster model without a form of animatable restraint?

Joli travail,

le châssis de l'attraction est très bien réalisé, merci pour ce plaisir :)

This is great so far! It could become a prefab someday, but not unless the following problems are fixed:

• The rear axle must not be covered by the flat bed of the train. It must be beneath the rear angled part of the train bed, and the distance between axles on multi-car trains must be equal in length.
• A car coupler chassis model must be made for the trains, in order for it to be added to the list of coaster types. The coupler hook should be laid on top of either the front and/or back end of the car. The entire unit rotates left and right, and features a socket in the middle for the coupler rod, allowing the coupler rod flex up and down.

You'll get a better understanding of how it works and looks by watching videos of Whizzer at Six Flags Great America and Montaña Rusa at Parque Del Café. Still pictures of the rides might help as well.

Best of luck to you! This is a really great concept so far, but it's still far from becoming a permanent addition to NoLimits 2.
