Dear dji colleagues,

When I fly in Attitude or GPS mode, atitude locking is not nice.
Please see the picture attached.
In wookong and naza I adjust basic vertical gain for that. What can I do in A2?



Kind regards,
Dmitry

In wookong and naza, after adjusting the basic vertical gain, how is the performance of the attitude locking like?

You do the same with the A2.  What are your current gains?

Hello, Tahoe!

Basic is 140 140 130
I think it help me to tune copter for wing, etc

Attitude  140 140 130
I think it help me to tune stick feedback.

And when the problem I mentioned -
in Naza helps "vertical gain" - it is basic - seems it for that.
But in A2 vertical gain is in Attidude - seems it only for stick feedback. Confused("

Heeelp)))

Kind regards,
Dmitry

I would raise the vertical gain in Attitude to 150.

Tested, nothing is changed(((

Help)))

How high have you gone on the vertical gains?  

Just to be clear, you will lose a little altitude when going forward and a fast pace, it should correct itself after a few meters.

Please list the type of craft and hardware being used.

Hello!

My setup is
Quadrocopter 0,85m, t-motor u7 490 kv,  t-motor 15x5, a2

I did not tried so much vertical attitude (only  130 and 150)

Kind regards,
D.

Try to up it..

I tested vertical basic gain from 130 to 230, it is the same((
Do I need to raise to 300?

How heavy is the craft?

How heavy is the craft?

It is now quadrocopter 16x5.4 u7-490 kv with 8 kg total weight.
It fly excellent, all is perfect - only this problem with attitude.
If with your help we decide it, it will be the best quadrocopter for canon mark.
You think - raise to 300?
Only this parameter (vertical gain) can help?

Can you hover in manual mode and tell me the throttle percentage it hovers at?

Calculator gave me 56%

Dmitry - I believe what you are experiencing is a change in pressure around the craft as it moves through the air. I have observed the barometric pressure reading will drop when you move the craft laterally. The flight controller perceives this drop in pressure as an increase in altitude and will reduce the prop speed to lower the craft to the 'correct' altitude. When the motion stops, the pressure goes back to normal and the craft rises back to its original position.

To test this theory, roll or pitch into the wind. You will see a greater or faster drop than if you were to roll or pitch with the wind. I thought DJI did a better job of fusing their accelerometer data with their barometer data on A2, but apparently not. It's far better than the open source firmware I was using with open source flight controllers, but not as stable as I had hoped. I believe newer generations of DJI controllers (Mavic, Inspire), are much better at resolving the conflict between accelerometer and barometer during lateral flight (or wind).

Bottom line, I am not sure you can do much about this behavior using gain settings.
