Hi guys,
I’ve built a few similar single-copters and always end up with yaw offsets / slight or aggressive toilet bowl effect on stabilize and alt-hold modes. I have jumped into PID tuning and filtering but I have not achieved stable flight. The problem becomes worse with bigger EDF motors. Also, the longer the flight time the more the pendulum effect is compounded. I have included my latest flight log for your opinion. Thank you!
