Did anyone notice this Rocky behaviour of flight with Avata 2 in the live view? Doesn't seem right. My avata 2 keeps rocking left and right slightly all the time even without winds... Please check yours... Look on the edges of the screen and it will show up. Rocksteady takes care of most of it but that isn't quite right... Madstech on YT has also pointed this out and DJI needs to fix this. This behaviour is quite prominent while the aircraft is in RTH. Request all to please check this by carefully observing the left and right edges of the goggles while flying straight. This behaviour was also displayed by Avata 1, but only during the RTH. It appears to be a genetic problem.

It will be great if all users of Avata 2 can check and confirm this behaviour. As more and more people report this, DJI may look into this and do a fix.

I haven't flown mine outdoors a lot yet since I have a broken leg, but indoors it's 100% stable just like the first one, if not more.

This happens only in the GPS aided flight. Outdoors.

lets put the mads tech video for everyone to know what its all about, at 9.12 min

yep i can confirm that. Tested it on a calm day. Small jittery movements on this axis.

Try RTH. It will be quite evident.

I believe this is normal behavior. RockSteady and HorizonSteady are applied to the recoded footage and not to the view seen in the goggles.
No wind conditions won't completely eliminate the need for the Avata 2 to make minor adjustments in the X axis; it will need to roll back and forth some.

Avata 1 did not do this and this is a weird behaviour. Doesn't make sense... It's not tuned properly. I would call this a BUG

Mine does. Even if there is 0 wind the Avata or Avata 2 will have to make roll corrections. Those corrections will appear in the goggle view and any recording made of the goggle view.

Avata 1 did not have this in Normal / Sports behaviour.
It does this ONLY during RTH.

Even if it is a weird behaviour, it's not acceptable.
DJI drones are known for their stability and flight characteristics.

This is tuning issue or a bug. It can be sorted with a firmware update.

The rocking behavior shown in the YouTube in post #5 takes place while the Avata 2 is close to the ground. Close enough that the Avata 2 is in turbulence created by prop blast hitting the ground.

Can you fly indoors without gps lock?

Yeah, N/S modes work using vision sensors (up to 20m on Avata 2 iirc). It's still perfectly stable as long as there's some light.

No. It's not the ground effect. Fly it 30 meters high and you will still see it. This happens only in GPS flights....indoors, it flies beautiful
Do an RTH, and watch the show

Yep mine is doing this as well.

More good information from this forum. Thanks to all concerned.

Are the DJI reps following this thread? I hope they are noticing this issue and are working on it.

I see some minor wind corrections in Normal mode and Sport mode; they normal corrections to keep the drone in place.  Remember that this is not a Mavic and doesn't have a 3 axis gimbal to compensate for roll or yaw..

But there seems to be an issue in RTH.  It's very prominent when the Avata 2 backtracks to the position where it lost signal.  I'm sure DJI already knows about this.  Here's a cool video where a guy almost lost the Avata 2 he was reviewing.

Hi, SaurabhSrivastava. Thank you for reaching out. Let me forward this to our relevant team for further checking. We'll keep you posted.

Hi, SaurabhSrivastava. Please check my DM regarding the topic we discussed. Thank you.

Have we decided this only happens when back-tracking during the FailSafe RTH and therefore it's not really an "issue" since we want to drone to do what is necessary and best during an "emergency" situation?  Also the Avata 1 has FailSafe RTH, does it rock as well?

In Avata 2, the rocking motion is there in all GPS modes even when flying in Normal or sports mode but it is less apparent. In RTH, it is more apparent and the Avata 1 also has this but only in RTH.
This rocking motion is not due to any external factors like wind etc. It happens even in calm weather. To me it seems like a tuning issue.

DJI has DM me saying that they are looking into this issue.

so its a known issue for dji and the tech team is trying to solve it?
i am asking because i am interested in buying a avata 2 but i want to wait to see how this issue is solved

Yes. Hopefully they will...
At this time, it's just wait and watch

Reply received from DJI :

Thank you for patiently waiting, SaurabhSrivastava. As per our relevant team, based on the video provided. The shaking may be caused by the near-earth flight being disturbed by its own vortex. The 520 gimbal itself does not have a roll axis, and the roll axis may shake if there is wind or other interference.

DJI seems to blame this on own vortex created by the drone which is NOT CORRECT.
I being an aeronautical engineer understand what vortices are....
This behaviour is apparent even at higher altitudes where there is no ground effect or self vortex without any winds.
This is very much apparent during RTH ATHIGHER ALTITUDES AS WELL

Requesting DJI to please do a proper test and revert with a solution. I believe this is a firmware algorithm issue and not due to any external factors.

Unfortunately the support personnel we can reach ain't very knowledgeable even about the stuff from their own manuals, let alone fluid dynamics. We need someone to make a succinct video showing and explaining the issue and to spam them until it reaches the right people.

(Tbh I personally haven't even noticed the issue yet in the few flights I did, so don't know how severe it is, but any regression from the old model should be fixed imo.)

This seems to be a different issue. The rocking motion of avata 2 is more seen during RTH, although it is there in normal and sports mode too.

I am still awaiting a concrete reply from DJI.

Mine is good on RTH its fairly smooth. The real problem is auto RTH, it turns around to where it lost signal first then it returns home. Very weird
