Is there a way to hack the train and track style into No Limits 1.7 so that I do not have to use the spinning coaster car sideways to get the same thing as the Uni coaster?

I had to do this to get my coaster to flip over like the Uni coaster does. I also had to look at the coaster with my head turned sideways or rotate the whole desktop 90 degrees.
