I tried this once with the MP over a soy field and made it 100 M and the next thing I saw was soy and sky. It was recording video and when I found it, upside down, and looked at the video, it showed a Hawk had knocked it down and then walked around it and stepped on it a few times before deciding it wasn't edible I suspect the grey drone at high speed must look like a good dinner choice. I have since applied a red and white skin emulating the Canadian flag and have had a hawk or two actually circle it while I was hovering, and fly close while I was flying and have never bothered it.
