Anafi FPV version and thermal vibration * solving the issue

[ParrotAnafiFan]

I am posting to team up with others to find and solve the vibration issue. I have heard and (experienced for myself) and seen videos of users with the strong legged version having severe buzzing sound while in flight compared to the original anafi. I own the FPV and regular version and you don't hear hardly any noise on the original version at all versus FPV type. Hovering it carefully in front and touch the bottom of each leg lightly, you can quite it and see which one is worse. You can tell the noise is plastic.

I have narrowed it down to these possibilities

1. The wifi receiver pcb panels are loose - tried a touch of rubber cement glue to secure them with no avail
2. The motor wires inside the legs are moving causing vibration and noise - no way to access the leg interiors to check, they are sealed.
3. The props - Not the issue as I have changed them and it still happens.
4. Antenna wires in belly are loose - not the case they are secured to grounding slot.

I believe they can fly quieter. If you have a solution or experienced this issue please chime in. I believe it to be #2.

Could older batteries produce a volt/amp sag on the motors and ESC causing it? Slight power dips on equipment lower prop rpm on the dual blade system?
