Rabbit 239 NX buzzing sound


After a forward flip I hear a buzzzzz sound coming from my quad .
I have to PID profiles profile 2 is it tune that diatone sent me. Profile one is similar pids are turned up a tad bit. PID Profile 1 makes the buzzing sound even worse after flips.
Any ideas how to tune buzzing sound out or what that is ?


Please provide a Video so we can judge that sound better.

Yeah im going need a video, I’m not sure what you mean by buzzing sound
any idea where is its coming from?


My D was too high.
I have 3 PID profiles. The second one I must have forgot to hit save in the CLI when I made changes to diatones tune.
They were way high on D.
