Hello,

I was doing some landing/take off in "high wind ".

All was fine expect I got a take off and imediate engine shutdown. AC felt one meter down.

Condition : heavy wind, take off.
Description : engine turned off after take off

I was pushing the drone to some "limits" but I think the flight logs could be usefull to DJI.

Cheers!

To me it very much sounds like the Spark got flipped 90° by the heavy wind and did the emergency shutoff.

Hello Diana!

Latest firmware ( AC, RC, Batteries and IOS GO4 ). No damage to the drone, it felt flat in the grass.

Cheers!

We downloaded the file from the link you provided, but only 1 log is visible.
Please connect the Drone to PC again, and run assistant 2 to export all the data in the list, it's appreciated if you could provide us the flight controller data as well, thanks.
