How do I twist a coaster 90' to make a top hat?

So I was wondering how to make a top hot on planet coaster I can't seem to make it turn 90' up then go down in a corkscrew I would love to remake Kingda ka but I can't so can any one help me out?
 
Instead of using the banking tool when it's vertical, simply use the right/left button and pull it in the direction you want it to spiral. When you smooth it out it get's the shaping both TTD and Kingda Ka have. I recommend changing the heartline to +1.
