Trouble on ESC or Motor?

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.

Here is the RCOU in flight

Post the .bin log of that flight.

What tuning have you setup?

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.
