Hoverfly Help... Is my Gain too High?

[Aerovideo]

I've had a problem with every multirotor I've built. Given that, it's probably my builds but here it goes...

I like to fly FPV and I like to fly fast. Whenever I get going or really just the the motor RPMs up there the motors start to pulse causing micro-bounces in my video. I've been successful at eliminating the jello and for most of my videos I just edit out the parts with the bounces. But for this video I left it all raw and included the FPV feed as well as the GoPro Video.

Frame: X525/Rusty Hybrid mix
Camera Mount: Rusty's floating camera mount with rubber vibration dampeners
Motors: Avrotos
Props: APC 12x3.8 (Balanced)
FC: Hoverfly Pro Green board + GPS (4.6r3)
Booms: Aluminum towel bars

Here's the RAW FPV video:

you can hear a motor not liking being alive that flight. Take your props off, fire it up and feel around for the offender.

There seems to be some serious beat frequencies. Vibration is most likely your culprit.

Isn't that beat frequency the FC controlling the motors?

You would think after all these years I would have figured this out by now

I thought the lazy osd was fixed? I was really hoping to utilize this on my next fpv rig. What about the voltage, is there a way to make that accurate, seems everyone has this issue. Try putting stiffer props on and see what happens, just as a test. like APC thins or Graupner 11's if those are enough lift. I doubt it's the issue but I see you have a clear dome and dont see any foam over the baro. Would that effect things? I disable mine and never have these issues, though I am also on the older firmware.
