Autotune don´t finish hexa

Need help to analyse why autotune dont finish. I set only roll axe. The copter enter in the autotune but after 12 min he dont finish yet. Very calm day. wind 2km/h.

The crash in the final of log was when the copter touch the ground. No damage.

The copter fly very well, but in the medium wind he twiches sometimes. im afraid and like to tune tog better recovery in the wind.
