Hi, I have a problem flying. The quadcopter that I fly always oscillate, even though they weren’t before. When I check the RCOU log, it shows a graph like this. I suspect it’s either the ESC or the motor that has a problem.
We see this output oscillation almost everyday on the forum usually due to default PID’s or as @Allister suggests a general tuning problem. There is not a hardware problem. The tuning guide addresses this, suggest you read thru it.
