AQ with 3 GoPros almost ends up in the ocean

This value is most likely much too low. What you have here is a lack of control on angular errors. This can either be too low mixer values (higher values = more power) on pitch and roll or a too weak PID controller or a combination of both. You can see in the video and from the logfiles that the controller needs to add high PWM values to correct the angle which is a consequence of a big angular error that needed to get corrected.

First increase your mixer values to higher numbers and then tune your PIDs. You will probably not be able to increase angle P to a high value since this usually leads to oscillation but I'm sure you can increase angle I to a much higher value. I fly copters of almost the same size (a little bigger) with angle I values of 0.005 to 0.006 (10 times more than the default value).

You don't have to fear that the the stronger values will produce a higher PWM addition which would lead to more/earlier saturation. On the contrary, there will be lower additions because the controller will not allow big angular errors to occur and instead corrects even much smaller small errors.

Thanks RW, I was able to fly with a much higher angle I value. The AQ felt as locked in as ever. I am hoping this squashed the gremlin. I will be flying more this weekend to see if it rears its ugly head again.
