Well, the flyer died because I learned how to do swing launches, so I've been obsessing on that for a bit now. I've put a lot of hours in to this over the past week (shut up Steam) and I think I finally finished the layout. I'm not going to give much away, besides a simple teaser, but my thought building this was this.
How compact/realistic could a swing launch coaster be that goes over 100 mph? Answer...
I made a B&M Hyper for scale
