I am operating a Tarot 960 built for SAR use (auw 8kg or about 17 pounds). It uses the latest stable fw for APM 2.5 (3.2.1). It has been flying fine for quite some time until now (it has been well serviced and looked after). For the last few days I have had some strange "toilet bowl" behavior in loiter mode. What's happening is that when I enter loiter mode, the hexacopter starts spiraling clockwise in larger and larger circles (and at the same time moving faster). It does this without any stick input. When I counter the movement it acts twitchy. As soon as I enter altitude-hold or stabilize mode it stops moving, and behaves as normal.
I heve redone the gyro and compass calibrations without any major improvement.
I am not new to analyzing the logs but I am sort of lost on this lone. I am sort of tempted to change the APM out for one of the Pixhawks I have in other test platforms but I would really like to understand what the problem is.
I have attached some screenshots from the log browser and the log it self (change the file ending from .pdf to .bin)
