Always Secure Your Batteries Properly 

Last weekend I flew 2 packs, one with the Peanut facing forward, and one with it facing backward. On the 2nd pack, I had not secured the battery and when I was inverted and nosed over (high negative G's) the battery came flying out and separated (3:56). Surprisingly, the wing righted itself, then made a nice descending spiral to a fairly gentle crash on the ground. There was almost no damage, and I even found the battery pack.
