Here's a short summary of your flight data:

It will give a lot more information than Airdata and you can view the joystick input.
Thanks for the info and link I will definitely check it out. I have been digging into the Airdata app to confirm what I actually saw. I did pull down on the left joystick at the end but it was because the drone was already dropping out of control and from what I saw the drone was already making contact with the water so I was thinking I could somehow cut off power and minimize the damage(I realize now it wouldn't have helped and would have been better off letting it continue to drop on its own). Just prior to pulling down I hit the RTH and it started beeping. I went to hold it down and realized it was already too late.
My main issue is that after I left go of the controls at 3:57.3 the drone continued to drop almost 2ft in 2 seconds according to Airdata Baro altitude. Sonar altitude showed it didn't move at all. Baro is closer to what I saw except for the Baro showed it was at 5.9ft when I hit the joystick down but visually it was actually just making contact with the water. The video shows how close to the water it was. I watched it drop straight down towards the water without touching anything.
There was another large drop earlier on while I was not touching the controls and I thought about bringing it back after I saw that and now I wish that I would have but I decided to do what I read in the manual to determine if the Downward Vision System was functioning. I pulled forward after the drop, allowed it to hover (which it did with no problem) and verified two blinking green lights.
At 3:34.3 without me touching the controls, the drone drops a total of 3ft in 7 seconds according to the Baro data.
I am new to drones but I thought they were more stable than this. I know the manual indicates many things that will mess with the Downward Vision System and that includes almost everything one might fly over(pure black surfaces like blacktop, tree limbs, water, etc). But I was under the impression that GPS would allow it to maintain stability if the signal is good. The signal was good in my case.
I don't know at this point. Maybe I am asking too much from the drone. Maybe the Mavic 2 has the stability that I am looking for. Not sure what to think right now. But again, thank you for looking for me. |
