My Avata sometimes decided to do some tricks without my input - usually, it's leaning left or going up - but till now I always manage to counter those sudden moves - till today when she decided to do totally uncontrollable pirouette up and backward my stick inputs did NOTHING this time - despite pushing the full throttle forward she flyes backward (see the sticks on the right) she come to senses after hitting a branch and flight continue as usual as also following flights my luck - Avata is safe

Have you done IMU recalibration? What is your firmware version?

Wow, Alex.  Flying back by itself is quite the anomaly.  Hope DJI can provide answers.

Is it possible that it has something to do with the moving water underneath the avata?

When possible, it will hold position with the bottom (vision) sensors... maybe they override the GPS?

looks like it is trying to keep it's location relative to the fast moving water for what i can see....

I doubt it as water is really slow compared to the rapid movement of Avata and also she moved upward, my theory is GPS related but who knows

I believe it's the bottom sensors causing this. Remember, when flying in darker places and/or over water, the sensors can't see the surface. The drone knows it's low to the ground because of GPS but because it can't see the surface of the water, it thinks it needs to save itself from crashing so it goes up and backward. If you are going to fly over water, this will most likely happen 8 out of 10 times. You can fly in manual mode and that turns the sensors off which would stop this from happening, however, you are getting dangerous if you do that and don't have a lot of experience flying manually. It's a good way to lose your drone to the water, so I don't suggest it unless you have been flying for at least a year in manual mode.

Hmm, I don't know then

But I would just about bet it's something to do with those downward sensors.

At that waterfall, maybe fly it again and stay about 10 feet above it and see if it does that again. Then if it doesn't go down low again and see what it does. I suggest that because someone above suggested it could be the movement of the water because it seems to happen right over the water fall white water.

Keep us updated of DJI gives you a solution, I'm curious now as to what may have happened.

I would refresh the firmware on the bird and calibrate IMU. Not fixed = DJI Repair

After 3-4 flights she did it again and it was an almost identical move - back, up, and left this time ended up hitting a rock and bouncing off it gave me back control
