Hi,
got problems with my S900 with E1200 Motors. The S920 starts swinging up and it's nearly uncontrollable.



I already changed the Motor rubber damper and cheked the blade balance, but no success.  
I'm using the E1200 Firmware 1.5 with the from Dji recommended Gains.
The first three batteries after the upgrade where fine without the swinging and than the swinging starts...

MY Setup is S900 with E1200 PP, A2, Lightbridge + 2. Groundstation, Futaba TG14 and Zenmuse Z15-GH4

Thanks for help
Best
Andy

Please check the IMU and GPS module mounting place and the compass value by assistant value, provide your assistant software screenshot if possible, you need to write the correct IMU setting and GPS setting according to the mounting position.
