Betaflight 3.3 has a feature called gyro overflow detection. It detects and prevents a bug in the gyro that causes your quadcopter to yaw-spin to the moon (also known as YSTTM).
If you aren't expecting this feature, it can cause you to think your quadcopter is defective. The problem that led me to this discovery is a person reporting their quadcopter would keep doing backflips even though it wasn't commanded to.
Fortunately, you can turn this feature off if you want to.
I'll show you what this feature looks like when it kicks in and how to turn it off if you don't want it any more.
