First DJI Mavic Pro 2 Crash Using Active Track 2.0!!

Check out the first crash video of the DJI Mavic Pro 2:

Please post your flight log so sar104 can tell us what happened.

He ran into a power line. Why in the world would you need a flight log?

The video I watched shows it on the opposite side of the road from the power lines and then it darts to the otherside of the road into the lines. Is that how active track is supposed to act? If so I guess there is no mystery.

Yeah that’s 100% pilot error, no way it’s reasonable to detect a power line.

 

[Talley]

Absolutely no way to detect power lines. Operator error

I don't use ActiveTrack very often, but when I did the drone pretty much stayed on the same side the entire time - it never crossed behind me like that.

Thanks for focusing on the actual issue.

Uh, that’s not the issue. The question is what made it decide to move in that direction?

Perhaps an inadvertent screen tap or button press on his part. Maybe low battery RTH kicked in. Maybe it couldn’t keep up with his speed. Or maybe there is a more serious software issue. Whatever it was, I’d sure like to know.

Don't be so reliant on "obstacle avoidance"

op was just lucky he crashed into soft plowed dirt,like landing on a pillow

Ok here are some more details. This is not pilot error. It was in active track with the remote on the seat next to me. No way to push any of the buttons. Speed was 10 mph. I believe the drone started to loose track of object and the new version predicts where the object is going. The mp2 predicted wrong and ended up circling ahead of me and around into the power lines. It is well known that the obstacle avoidance can not detect power lines and that is not the issue. The problem is why did active track decide to take this route instead of maintaining the track of the object at the side profile.

lol next time set at a obstruction clear altitude.

That definitely sounds like the most reasonable explanation, especially since there is no chance you hit any buttons or the screen. So any chance you can post the logs here? Are you comfortable with that?

Meantime, I think this thread will continue to get posts about wires and obstacle avoidance. Just have to ignore those and focus on figuring out why it moved in the direction it did.

 

[lil Glock]

If you put it in activtrak you are the responsible party there for you are the pilot. You put it in altitude with nearby power lines occupying that space. That's pilot error.

However it did appear to lose active track tracking. So there is that .

 

[JDawg]

OP- Please post your flight logs and avoid the 'noise'.

 

[BobGriswold]

Do you retrieve the logs the same way as the Mavic pro?

I think these are what you are looking for, I copied them from a post by sar104, a Jedi Knight.

100% operator error. Reckless, did something stupid, lost the bet.

 

[Dmbrody]

Wow. These posts just keep coming.

Guys, enough already. Stop trying to assign blame.

• The OP already knows obstacle avoidance doesn’t work on power lines, thin branches, etc.
• The OP knows that no accident would have occurred had he positioned the Mavic higher (or lower) than the lines.
• The OP knows that had he paid closer attention, he may have been able to prevent the accident.
• The OP isn’t trying to blame the Mavic or DJI or anyone else.

What the OP doesn’t know is why the drone made the movement it did. Why didn’t it continue to track him from the side? Did it loose active track? Was there a sudden GPS glitch? Did a magic fairy cast a spell on it? A look at the logs will provide the answers.
