Hi Colin,

Looks like you’re using 3.5.7, this category is really for 3.6 which is undergoing beta testing so I’ll move this report.

I can see a bunch of big spikes on your Z acceleration when the problems started. I think something has come loose in your aircraft. Maybe your flight controller has come a little loose or something has moved and is able to bounce against your flight controller.

In any case your low frequency accelerations on Z have went through the roof and the EKF is complaining.

There is no reason to think that there is a problem with autotune here. Auto tune does not change your PID settings until it has completed and you have landed and disarmed in the correct way. All this has happens on your manual tune. I strongly suspect a mechanical problem here.

Let us know if you find any more information.
