I ran a quick test in a few minutes flight to verify that the flight mode altitude hold is inserted.
Ok, it works.
Probably flying the quad will of vertical oscillations; to what extent these oscillations can be considered acceptable ?
I set the altitude hold parameters according to this guide (see attachment)

Try setting AltitudeFilterSettings > BaroKp to 0.02

Here is a video from test i did with this settings:

Thannk's for info.
This parameters

AltitudeFilterSettings > BaroKp to 0.02

set the sensibility of Barometers?

[f5soh]

Not the sensibility but better filtering

[startrek66]

Test flight with positive result.
With altitude hold engaged and without comand (pitch, roll or yaw) the quadcopter mantain the quote with minor oscillations.
When apply pitch and roll the quadcopter  loses altitude but not in a major way.
My question is:

If the quadcopter loses altitude, the Revolution tries to recover the initial altitude (when the altitude hold is engaged)?

Yes, altitude target 'stored' still the same.
