I would appreciate your help adjusting the aero unit for a smoother landing
I want maximum stability and low response to the transmitter commands
To get this I lowered the default Direction Control Rate in the Stabi tab to the minimum.
And also lowered the Feed Forward value in the Advanced Tab
With this adjustment I obtained a reduced TX control and smooth landings
The problem is that the plane does not control well the height, it presents slow variations of 30 centimeters up and down near the ground
Please advise me how I can get a stable height control at the landing
Maybe raising the gyro gain?
Thank you

For the lack of comments on my post, I guess I do not write it in an understandable way, so I attach a copy of a post on the same subject, I hope it serves

Hello,

I am very sorry for not replying your question.
Unfortunately we are very busy with development and your question was overseen.
So if you ever will not receive reply in 1 day, then please send there additional message which will send us notification.

Definitively I recommend to change Gyro Gain (especially for Elevator axis). If you already can see some kind of bouncing, I recommend to decrease Gyro Gain (elevator axis). Since it is trying to achieve precise attitude all the time it is trying to do so as much as possible. But without speed the movement is too big which is causing bouncing.
So I recommend to decrease Elevator Gain at least by 20-40% to make it smooth.

Ok, thank you for your answer, my landings are now much better, no bouncing at all, no landing damage
