A reddit user recommended calibrating my IMU (despite it showing as normal) when they saw my avata jerkinng and flipping over in manual, and it's made a world of difference.  If yours is doing something similar, might give the calibration a try.

Made a quick video showing the difference:

Hello there sirnumbskullgmail.com. Good day and thank you for sharing this video with us here at DJI Forum. Have a safe and a happy flying always.

Definitely made a difference on your drone.  Thanks for sharing.

I hope that they will release a patch firmware to fix such sudden misbehavior when using manual mode. A lot of avata users are also complaining and experiencing such misbehavior when yawing their drones causing big crashes.
