it's a known issue; posted all over the forum for weeks now.

It was good that you were pretty high and you could get it back stable. For the moment is better to do slow turns. Hopefully DJI will fix this well known problem soon.

Yes, well known by now...   

Yeah, that is a common issue right now.

Hello there Cesar Murillo. I am sorry for the trouble this has caused and thank your reaching out. The DJI Avata has an onboard propeller guard, which enhances the safety performance but adds certain resistance when the DJI Drone fly sideward. Provided that the DJI Drone does a sharp turn in strong wind or sideways emergence brake whilst in flight, those movements will incur attitude errors. Considering the scenarios above, kindly please fly with caution. Thank you.

This is more proof that DJI needs to fix this issue with the Avata.  Yet, they remain silent.

Hello ,  let me show you the black box ,  no failures message , no different indications , full GPS signal,  only I can see Abrupt change of heading    .  May be aerodynamic effect , but the avata it’s very expensive for that results !
