Sorry I haven't posted here in a while, but I'm going to try to explain to you step by step how it works.
1) Passengers load into coaster trains that are being "held" within the ship.
2) The ship starts to swing back and forth. Passengers are then sent into a 90 degree up one side and then as the ship gos backwards for the final time, the ship goes into the 90 degree angle but what happens is that is when the coaster train drops out onto track and then sent over some LIMs to keep its speed up and then it goes on the complete circuit.
3) The ship is being held steady by a "harness" holding it up from the back town holding up the ship and coaster tracks.
I know this can work. I'm building a model and when I finish the whole thing, I'll post the pics here. I would like some feedback. I know its a complicated idea but if it ever was built, I know it would be amazing.
