BetaFPV Shock-absorbing Camera Mount

This is my second attempt converting the Pavo20 from the O3 to O4 lite. Initially I was having problems with heavy vibration in the video footage, and I was not sure if it was the tune or something else. So, I gave up on the conversion and moved the O4 to a Flywoo FlyLen85 frame instead. I am sad to inform you that it went flawlessly. The video footage is practically free from vibration and jello. With that said, here I am trying to install the O4 again. This time I am using the BetaFPV's shock absorbing camera mount. This camera mount seems to improve the Metero 75 Pro O4 video quality, so why not try it for the Pavo20 too.

This time around I noticed a major issue that I missed during my last build. The 3D printed air unit mount was sandwiched against a screw, which prevent the top camera cage from isolation itself from any vibration from the rest of the quad. Therefor the top cage did not have any vibration dampening. As you can see in the picture, I file off some material from the mount so it will clear the screw. I updated the 3D file so what you see in thingiverse does not require any filing to make it fit.

Another big change is the new BetaFPV camera mount which has its own vibration dampener too. At first, I was worried the camera would sit too far inside the cage and record the prop and camera guard in the video footage. To my surprise, none of those items are visible in the DVR or HD recording.

BetaFPV O4 Air Unit Bracket for the Pavo Femto

I did not like the results of the video footage and once again I was in search for another fix. I am sceptical that a the BetaFPV Femto would make much of a difference, but I tried it anyways. I guess I could not hurt to try because it was only $5.99. To make a long story short, the Femto cage on a Pavo20 frame made the video footage even worse. Also, the included short antenna has less range than the original DJI antenna (slight difference, but still noticeable).

Switched back to the Pavo20 cage and add weights to the camera

Right after I switched back to the Pavo20 cage, I saw an improvement to the flight footage, but it still did not fix the problem. The next idea is to add some Ummagrip Universal Sticky Battery Pad to the top and bottom of the camera as weights (about 1 gram total). I felt the bare O4 camera is too light to utilize the vibration dampeners, so I thought some extra weight with help with it.

Video footage with weights added to the camera. (SUCCESS)

To make sure it was not a fluke or something else that fixed my issues, I removed the weights, and the video had lots of jello and vibration. When I added the weights back on, it fixed the video the issues. The PID tune I am using is still from the stock BetaFPV Pavo20, so it needs some work and you can see it in the video. The main take away from the video is to see the improvement over the previous build attempts.

Current BetaFlight and ESC setup

Betaflight........

ESC firmware updated to: BlueJay v0.21.0 48kHz. When I updated the firmware I did not notice the Comman Parameters is not using default settings. What you need to pay close attention to is the Minumum Startup Power (Boost) and Maxium Startup Power (Protection). Because when I left it at the default settings, the motors would not turn. At first, I thought I bricked or fried it. I was lucky to have another PAVO20 and I compared the settings. Make sure you set the Minumum Startup Power (Boost) to 1125 and Maxium Startup Power (Protection) to 1200.
