Change in Autotune parameter save behaviour?

In Copter 3.x it was possible to switch to LAND mode after a successfull Autotune flight. The copter landed and on disarming it saved the new parameter values. This was definitivly so, because I did that very often.

In Copter 4.03, as soon as you switch to LAND flight mode, the copter immediately discards the new Autotune values and restores the old parameters.

But I cannot find any documentation that this behaviour was changed?

i can confirm that this behavior has changed in AC 4.x
pilot must land with autotune flight mode or you can change to LAND flight mode and before disarming motors change to Autotune again then disarm copter to save PIDs

Oh, this is clearly a disadvangage. Maybe the devs think about reverting this behavior back again to as it was in 3.x.

I agree I liked the old behavior. Was nice not to have to worry about things and just switch to land and have the quad land itself saving tune params.

Me too. Pre 4.x I would do the autotune then switch to stabilize to land it with the autotune switch high and it would save the PIDs. Now if I change flight mode it will discard the PIDs.
