I'm in Honalulu on vacation and couldn't wait to fly drone. The 1st & 2nd flight went well. On the third battery I flew fine and was landing where I had the problem. I didn't want to land in the sand so I hand launched. I have launched and landed in my hand a few hundred times in the 3 yrs I've owned it with never an issue. Once in my hand the drone went crazy. It revealed up and would not stop. Nothing I did stopped it. I made the mistake of trying to remove the battery but the props got me good. Bleeding from 3 fingers, I let go. It did hit the ground hard then stopped. All of the flying, I never had this happen. Any ideas???
