I sent them the video so they could see the drop... their response was that they could not match the video up to the data as it was not from the drone itself... so they could not be sure that when the drone hit the water was when the flight log ended.
They did not even mention anything about the loss of height due to braking.
Their analysis (if that is what you can call it) was very basic. They did not look into the detail as much as you did. The went more down the line of 'we can't pull the data off the drone and the flight log stops...
Hi All,
Wanted to drop you a quick update.....
After a considerable amount of time and effort (lots of correspondence to and from DJI) I have managed to get this replaced under warranty today... so almost 2 months after they had received the drone to investigate the issues.
They could not...
@sar104 I have managed to get the footage from the other drone that was flying that day and you can just see my MA in the footage as it flies and then drops... if you look carefully! I have zoomed into the footage part way through to make it easier to see. Have a look and see what you think -...
Ok thanks for your help @sar104... seems like the conclusion is I was too close to the water then at the end of the day? I still don’t feel the data is showing what happened as the three of us watched but I have no explanation and what you have explained makes perfect sense.
Thanks again, will...
Thanks again for detailed reply and highlighting various bits. So from the above I would add that I think the abrupt entering of the elevator may have been when I saw it in hit the water.... as from what I remember the only action I did after that was apply full up throttle to try and get it...
I do have the DJI Care Refresh which is something.... however I don't feel I should have to use it which is why I wanted to get some expert advise as to what the flight data reveals.
They didn't want paying!.... I offered but they insisted that they wouldn't accept it. So I donated some money to their Scuba Club and get them a cash to buy themselves a beer which they finally took. A great bunch of guys that I was lucky to find. Still nice people in the world :)
At the time it was around 1.5metres above the water I would say. It also dropped like as if it had no propellers spinning... it seemed to drop visibly faster than if you pulled down on the stick! There was power to it however as when it was in the water I tried to lift off with no success.
It was flying level at the time, for the final (approx) 4 - 5 seconds of flight, just forward motion... then dropped into water. It still had visible power for probably around a further 3 seconds or so once it was visible on the surface of the water.
It was around 1.5 metres above the water moving forward, not up or down). It suddenly dropped and splashed before sinking. It wasn’t lowered into the water, it was a sudden drop, as if it lost all power.
thanks for your help with the flight log... I have found the drone and updated the thread with a little more info. Thanks very much for your input, appreciate you taking the time to help.
