QUASAR!

Quasar is a unique Schwarzkopf shuttle loop.

The train is launched to a speed of 65 mph before going through a wild tilted figure 8-ish element, pulling up to 5.3g in the lower half. The train then goes through the 90 foot *circular* loop, pulling up to 5.6g, then going up the 75 degree, 170ft tall front spike, before doing it all in reverse!
