Rotorgeek 20A timing test (CM2204 2300kv)

I am testing higher timing on my new RG20A ESC's. Comes standart with medium timing, in this video they are running medium-high, with no sync issues or anything on Cobra 2204 2300kv.

Unfortunately i am having oscillations on my mobius recordings. I don't know whats causing them, perhaps a motor is out of balance from a crash? I can't psycially see the oscillations when looking at the quad in the air, neither can i see them on my flightcam. Feel free to comment if you have a suggestion to whats causing this.

Setup:
KillerBee
Cobra 2204 2300kv
RG20A (BlHeli 14.0, timing: medium-high)
Naze32 (cleanflight)
1000mah 4s
