I forgot to add this yesterday.
I most likely forgot the stuff I wanted to point out about it. Anyway, I tried to clean it up a little compared to the original.
I will say the compass reading is dead on, or very close to it. I consider myself to be above average in knowing how to use dashware. And this video was tricky to do to because the visuals in the video with what you see an the display on the compass reading were really strange in this vid. The compass reading....is the actual direction in which the P3 is pointing, which is most parts of the video is totally different then what the camera and gimbal are doing.
The gauge I used in this video is my favorite. On the graphs each display what the P3 has done or is going to do. With them going down or spiking upward you some idea what is coming in the video. Also on the far left is the mapping display and the top is North, bottom is South, and so on. When you see the compass reading pointing at the North, look at the mapping display and the P3 will be pointing or traveling to the top.
At the end I added slow-motion to better show things that are hard to see in real time. Example, I noticed the props on the front of this P3 were working at similar speeds. At no time was either of the two not rotating.
After watching the video and looking over the data it's my opinion that the P3 had a compass error. The crash itself was likely due to repeatedly being switched between GPS and Atti modes which of coarse corrupted the flight. Most have no idea the kind of adrenalin rush you experience when you see your craft doing something it shouldn't be doing. Then knowing it is over a large body of water would only add to the fear.
