I don't have a track I can post right now (I have one but the file is too big), but I did a simple test where I came to a hover a few feet off the ground, engaged position hold mode, and then made a few very slow and gentle left and right turns. What I noticed is that the yaw autopilot seems to be making a sudden erroneous input in the direction I'm trying to turn which destabilizes the heli.
Luckily I also recorded a video of this:
Pay close attention to the green autopilot yaw channel indicator on the controls overlay when I start my first turn at 0:30. I'm very slowly and carefully applying left pedal and the autopilot keeps fighting me, and then at 0:44, you can just about see the autopilot make an unexplained yaw input to the left which causes the nose to snap to the left.
And then again, at 1:14 when I'm trying to make a right turn, the autopilot makes a sudden input to the right.
And again, at 1:42 when I'm trying to make another left turn, the autopilot makes a sudden input to the left again.
Can anyone else test this and verify? This is on latest Open Beta.
