I use 1.1.73 and AC 2.5.4
If I check Tune CH6_Loiter_P the Loiter P don´t change, it Changes the Loiter speed.
In what unit is Loiter speed? m/s?
And is Loiter P with 2.0 default normal before it was 0.5... or so and now Loiter P is 2.0 and Loiter speed is 0.5... or so, Could be there anything wrong?
are you sure you have selected the right option? what about
