I don't know how EXTRA won his but last summer my club had a "Family Day" event at the field. Fun fly, food, friends and door prizes. Open to all members for free. This is the door prize I won:

Haven't put it together yet, been too busy with other stuff and having to get accessories together for it.

FREE! The best way to win things. All I had to do was show up and have fun.
