also If you look at the log the VPS altitude shows on the last location 14ft , which tells me it could be crashed in some tree/or property and the IMU could just be bugged . This is frustrating I guess I gotta get an inspire or something better that can hold the wind. its only 20 mph ... I'm not sure where you think you saw 14 ft ... it's not what the data says at all.
The last record shows the altitude at 410 feet and the VPS showing N/A.
It was high in the air and flying at 4 mph.
There's no hint of a problem with the IMU but there's plenty of evidence of pilot error.
did search the place and is not there.
That's because at the time, your drone was 400 feet up and flying further south at 3-4 mph.
It appears that you lost signal and we have no way of knowing what happened after that point.
Except that we can see the drone was at 15% battery and would have autolanded soon after when the battery reached critical low level.
There is no terrain that the drone could have crashed into on RTH so wind is the next obvious potential issue to investigate.
There were warning signs all over the flight data which starts with the drone 565 ft up and going backwards at 2-4mph in hands-off RTH with the battery at 50%.
After a while you tried sport mode for nearly 2 minutes and burned the battery to 36% for a gain of only 200 ft and gave up on Sport Mode.
You went back to RTH, sometimes adding a bit of right stick but just ended up even further away and with less battery.
It wasn't till 10:30 that you started bringing the drone down lower and started gaining distance.
However you still left the drone 410 feet up where it was fighting a strong headwind and hardly gaining.
Then the data ends with the battery at 15% and the drone 2800 feet away.
It's a tough lesson but maybe you've learned that the wind up higher is always stronger.
Leaving the drone up so high was a big mistake.
If you'd brought it down to 100 ft early on, you could have easily made it home.
If you had realised the wind speed and direction and flown the opposite direction instead of flying away up high with a tailwind, you'd have had an uneventful flight.
About the best anyone can do is to advise that the search area should be between the last recorded point and home.
I'd start at the halfway point and work southwards - but it doesn't look like an easy search. |
