... not a bad one fortunately. Low speed and low altitude. I finished up flying and it still had a little battery left so I decided to bring it inside and terrorize my old lady's dog. (For some reason he does not seem to get as much joy out of the Mavic as I do) Anyways I was hovering a couple feet above the ground and I guess it lost the GPS signal because it seemed to not be stable all of a sudden and it drifted and one of the props caught a table leg and down she went. No damage other than a small crack in one of the props. Needless to say I don't really fly it inside now!! Other than that I am loving this. Watching the footage is almost as much fun as recording it! I love how stable it is. And it looks cool in its new skin too!!
