I don't know if anyone has tried to re-create Raven Racer, (I don't know why you would) (raven racer is one of the premade hypertwister coasters on RCT2) but is impossible. At the very end of the ride there is a turn that goes up into a uphill turn to the brake run into the station, but that little thing before the uphill turn is impossible to make. I would add a picture but I don't have much time.
Its easy to make. Start with a banked turn, any size. Then, select the small radius turn. You will see in the angle selection area you can now angle it up. Select it, put it in, then the next peice of track will be a small radius upward unbanked turn.
