RTH Crash

[ChrisSask]

I have had a Mavic 3 Classic since June. Yesterday I was flying and the drone fllw on the other side of this shelter. It was 1,095ft (333m) from me when I lost signal. Instead of going up to RTH hight (25m), it continued going straight for 141ft (42m) and crashed into the side of the building. It was in sport mode with accident avoidance off. It was recording at the time, but that video, won't open. The rest do.
Has this happened to anyone?
****EDIT**** When I say happened to anyone else, I'm asking both recover video and it crashing with RTH.

Assuming when you say, "Has this happened to anyone?" you are talking about the inability to play the truncated video. The video got truncated because it was not stopped gracefully. That has indeed happened to me. The video is recoverable, but you will need another example video from the same memory card that does play.

There is plenty of guidance on the internet about how to repair a truncated file.

Thanks.. I was asking both about recovering the file and crash when RTH

There are people on the forum who can help interpret the flight logs if you'll post them. That's the best way to understand what happened. Otherwise, it will be guesses and conjecture.

Not to be off topic here, but I wonder why DJI would not automatically turn on obstacle avoidance in the event of RTH

Welcome to the Forum!

#1 don't sync your mobile device to DJI yet.

#2 look at this thread.

Mavic Flight Log Retrieval and Analysis Guide

With the introduction of the Mavic Mini there has been a noticeable uptick in the number of posts requesting help with lost or crashed aircraft. While there is plenty of help and advice available on this forum, and detailed guidance and options on several other websites, I thought that perhaps a...

Other members will help out also.
If you got questions you will get help.

I wouldn't say off topic at all.... it definitely should turn it on.

What makes you think they don't?
At the moment we have no information to say that the OP's drone was in RTH and we don't know if he had obstacle avoidance enabled.

Yeah... share the flight log so we have all data.

But just so you know... if you flew full speed in Sport mode (21m/s) & lost signal it would first brake then go into RTH... & you were only 2sec (42m) from the building, really doubt your drone could brake to a stand still under 2sec (if you had full speed).

In regards to the "corrupt" video . . . . there are programs you can use to "complete" the video but ONLY if you don't do anything else to the SD Card.

Once you’ve downloaded the flight logs you could try powering up the drone and recording another video. I’ve done this when a video hasn’t completed and it’s fixed the problem

Well, if the height of the building is, let's say 100 feet high, your RTH should reconfigured for the height of the building and another 50 ish feet. Or just Hoover, walking to the area that the drone is and you might get the signal back. Also the antennas should be pointed to were the drone is. Using situational awareness you can mitigate before flying the possible issues in that mission. Perhaps you need a VO.

Just to clarify to avoid any confusion....the antenna tips should not be pointed at the drone, but rather the longitudinal flat side.

And to clarify even further, the Mavic 3 Classic remote controller does not have protruding antenna tips. The top of the remote controller should be pointed toward the aircraft like this:

Thanks....I fly a M2P and am not familiar with the Mavic 3 Classic.

To further clarify, I fly my Classic with the RC Pro. You can also use the RC-N1. You are referring to the RC ONLY.

 

[msinger]

You are referring to the RC ONLY

Indeed. I hope nobody is trying to point their drone at their drone

Correction, the antennas should be pointed in an angle or completely up or down. Wen the drone is located, if is on top of you, antennas up, If is 45 degrees from you then a ten as in an angle, if the drone is flying low or directly in front of you the antennas flat down. Also one antenna up the other down or in an angle and the other up, depending on the movements you are doing. In my case as Im inspecting a cel tower that is in front of me, then the antennas are up and in a 30degree angle.

@ChrisSask,
Are you still part of this thread?

Rod ..

Adding, sorry I guess you have only been on here for a day, I will be quite.

When I had a similar video interrupted while shooting, and it would not play, my solution was to shoot another video onto the SD card and it would finalize the previous one to enable playback. Worked for me.
