Get to the Choppa!G 10

After the tutorial and you are on the mountain you can switch to chopper any time by pressing the Y button to fly around and find runs to compete or complete in. You can do this in under ten minutes pretty easily, the mountain is a box, just fly to the edge and when it says return to the course pull back until you are in and the message goes away, then follow it around and you'll have it done pretty quickly. I hear the you can also unlock this why you are creating/editing a run as you will be in the chopper while you do this.
