Video Description:

During an event; pull off a 1080 forward or backward rotation in a single jump.

Settings: Trial mode - Freestyle Race (Sandy Mountain)

Build up your boost prior to the big jump, use your boost and make sure you pre-load off the jump. Once in the air tap up or down twice on the LS (depending on if you want to do a forward or back flip) to get your flip going. Once you have completed three rotations square up fr the landing and the achievement is yours. I was not able to do this until I upgraded my quad past the 6th Stage.
