Air Hogs introduces the "ducted fan" Helix X4 Stunt Quad which I predict it will be a popular item due to its unique design and durability. Sadly, the Storm Launcher days are gone. It was a popular item from Airhogs about 7 years ago, but this quad will undoubtedly make up for it. It is really fun to fly and virtually indestructible, being able to do very wild maneuvers. Here are links to their website for more information. Spinmaster.com Airhogs.com
I purchased mine from Amazon.com
