Flatspins are pretty hard to do on a tramp, you usually need some forward momentum like jumping into a pool. But you jump, and kind of throw like a corked, except you throw your back into the spin so your knees come tucked up and your ass is pointing towards the ground. You're kind of horizontal in the air, so look back over your shoulder to spin, and twist out of the horizontal to land at 5 or 7.
