I’m having a small problem with a 250 quad. After changing the propellers to have less noise and tuning the pids accordingly I got a nice flight. Especially had to lower the P. Now after a week trying again it is not working anymore. It looks like trembling and I have no control over it. Looking at the logs I see that the motors 1&3 are alternating to 1800 and motors 2&4. Not sure where to look. I’ve tried adjusting the pids again, but not finding position where it goes away. Any clues? Thanks!
