Dji Pilots please be aware that today i was flying with my mavic air in tripod mode at 3.3 km/hour. Suddenly mavic air changed direction and was flying towards me with 76 km/ hour (still in tripod mode)
Mavic air limits in sport mode are around 68 km/ hour. Does anyone had the same issue? LUCKILY NOBODY GOT HURT WHEN MY DRONE CRASHED WITH A BUILDING AND FELL DOWN

Hello there. I am sorry to read and to know what happened to your DJI Mavic Air. This is not the experience that we want you to have with DJI. Since there was a crash and this unfortunate event happened. It would be best to contact out DJI Support Team for further assistance at https://www.dji.com/support?site=brandsite&from=nav . We would do their best to find out the reason of the incident and then the corresponding resolution/fix would be provided. If the said drone is still under the warranty period and it is evaluated as a non-pilot error, the warranty service will be provided. Again, I am sorry for the incident and thank you for your understanding.

So sad to read this. Good luck next time

Sorry for your loss, it sounds like it could be a Yaw error.
