Dusk flight this evening, all going well until I could see the quad swaying about so started to descend at which point, when I could see her clearer, she then starting pitching about too. Anyway, she landed fine, no damage.
In the video, you can see the front right arm dive across the front of the camera lens which is clearly indicated in the log, then a minute or so later, the log shows her pitching quite badly for about 30 seconds, she's fine after that.
I have been tuning the gimbal which carries a mirrorless camera so all up, the gimbal weighs >1.5kg so quite a heavy load although the quad is X8 with up to 20kg thrust. Initially I wondered if the gimbal had pitched violently but the camera holds level.
If anybody knowledgeable on logs could have a look, that would be great..
Thanks.

There a massive echo in here..
Anyway, this is solved, I believe. The lower front right motor has a bearing rumble so I suspect that lost power/bound up somehow which is why that corner dipped so badly until Pixhawk caught it and corrected it. Thanks Pixhawk, nice catch!
Will replace the bearings and so how that goes.
What I thought was strange activity in the tx/rx log is normal apparently so no problems there.
Does this graph show Pixhawk battling to save my Spyder?
The Graupner tx/rx log shows some strange activity at this time..
