One CT that's on my bucketlist is Kennywood's Steel Phantom. The original from 1991 to 2000
This one will have to be done by scratch, but there is a video out there showcasing a nolimits version. The download link for that one unfortunately doesn't work anymore as the site had closed down years back.
Unless if anyone else still has the file, it will have to be done by scratch. However, If anyone can pull it off from scratch in the original NoLimits program, I'll be amazed by that. The full second drop, which is 225 ft goes straight down into a ravine.
Length: 3,000 ft
Speed: 80 mph
Height: 160 ft (first hill)
225 ft (second hill/drop)
Loop
Batwing
Corkscrew
