QQ190 Bad Oscillation
I reflashed the QQ190 threw betaflight now it has really bad oscillation as soon as its armed, you can bearly hold it in your hand with no props. I tried to turn down my D rates, that helped with the oscillation but when it arms the motors spool up to full throttle.
Fixed! I finally got it fixed! It turns out I had my motors out of order to the Betaflight config. After switching the motor layout and matching 1-4 in the correct orientation with BF and doing the calibration again. I am now flying smooth. Just wish the esc were a bit stronger.
Are one of your motors getting hot? Sounds like a similar problem I have been having. Can’t help you out with any info though as the guys who make this drone are a goddamn joke, been waiting weeks for help
