A flat spin is a spin done horizontally in the air.
A flat spin is a spin done horizontally in the air. To do these, you need to be able to get a good amount of air, so that you can execute the trick.
Pump hard up the ramp, and give your transition a slight curve, as if you were going for a grind (the way you want to spin). As you start to air, you will feel as if you are lying on your side. At this point, you want to bring your legs round hard, so that you start spinning. This will get you rotating around your belly button (if you do it right), and all you have to do is hold the position, until you have gone full circle, at which point, you will be facing away from the vert. Here, you want to give your torso a little twist, until you can see the transition. Just brace yourself for the landing, or the bail, depending on how you end up.
