I'm working on a B&M out-and-back hypercoaster, inspired bye SilverStar and Goliath. Its height is 86m and I Wonder ir 2400m for its lenght is too much or it's just ok for this type of track? It also has a water splash at the end. Thanks!
I don't think there is a concrete maximum length but if it's too long then it might get real slow-paced and repetitive at the end. According to Windows calculator 2400m is 7874 ft, which is longer than Fury 325. If you're going for realism that seems like a little much even for the height that it's at, but if you don't care, that might be okay as long as it doesn't feel like it drags on and on pointlessly and it can run at least 3 trains without major stacking.
^ With that length you could probably push 4 trains if it was blocked properly.
As for the track length, it's hard to say. Hyper coasters would usually have a lot of airtime hills, which can rack up the track length pretty easily. Could we get an overview of the layout?
