The quad copter performs quite well when I disabled optical flow sensor. However when I enabled the optical flow sensor, the quadcopter began to vibrate. Is it due to the reason that the altitude is out of the test range of the range finder? Here are my flight logs. Please view them below.https://drive.google.com/file/d/1iN_KjdpwTZzEnMkd7k5nQnLVVzi9FU4W/view?usp=drivesdk https://drive.google.com/file/d/1N7tornxrpsz_nq5RJA_i0-Y3GN97Ft2F/view?usp=drivesdk

For the second log:
The instants of high vibrations coincide with CTUN.ThO reaching high values. VIBE.Clip0 and VIBE.Clip1 also increase then.

Are you using the harmonic notch? There is definitely a problem between the harmonic notch and EKF when using OF. I have not been able to get to the bottom of it.

Quite similarly to the video except that I used loiter mode.

Interesting finding. I think this is probably due to the rangefinder. I did several flight test
Ok,I’ll try that tomorrow. It’s dark outside now. Thanks, bro.

I don’t think I have a harmonic notch. Is that an additional device or is it built in the flight controller?
