If anyone can, try to make one and pm me the file!

Be more specific. I mean am I meant to really give up my free time to PM you a file for you to then say "That's not what I had in mind!"

Any feedback and ideas areappreciated.

well the track would look like the knex coaster "Screamin' Serpent", which that track has 3 rails like a corkscrew track, and i would like it to have upside down loops and an upside down chainlift options like from "Serpent's Spiral". The support beams look like a woodie but are made of steel instead of wood. And also it be cool if it could be like a flying coaster with upside down helixes

Im really sorry, but my sister broke my rct2 CD a few months ago, so I cant help you. But i have the screaming serpent roller coaster at home.

dang, that sucks.
