My aircraft has significant vibration on the roll axis after takeoff. The wingtip shaking is clearly visible. I’ve tried reducing the roll axis PID to the point where the shaking is no longer visible to the naked eye, but now the P value is 0.07, which is far below the default. I’m wondering if this will cause any issues. Can anyone help me resolve my confusion? My VTOL aircraft weighs 35kg with a 4.6-meter wingspan. Also, when I check my logs in the ‘ArduPilot Filter Review Tool’, the vibration amplitude at around 12Hz is -33.88dB. Do I need to worry about noise at this frequency?
