The rolling fury has pretty much disappeared as it was a 2007 model I believe. Air Hogs in general are very hard to find, but your best bet is probably a SuperTarget store if they have those where you are.

The rolling fury is good for about 1 weekend of fun, then it is time to move on! Or atleast that is my experience. They are tiny and will only take about 2 mph wind before being hard to manage. You will probably frustrate yourself as much as you enjoy the little bit of flying that you actually did. I wish I had a picture, but you should have seen me (48 year old man) 25' up in a pine tree trying to shake down a $20 plane...

Your time would probably be much better spent trying to find a local RC club/field.
