Just some observations from the log.
All the motors are working pretty hard, 1600 to 1900 mostly, and that doesn't leave a lot of room for good stabilisation.
Your Zmag on compass 1 has quite a few spikes which is curious, as compass 2 is relatively clean.
Zacc shows quite a bit of noise, although not what's regarded as critical, but it won't help.
Looking at des.roll or pitch against actual shows an aggressive response.
Could this be the reason for the high RCout values?
If the copter is over tuned it will hunt around a lot.
There is definitely more noise on the Baro1 than Baro2.
But the Des.Alt and CTUN alt follow one another ok.
I would look more at the aggressiveness of the tune and why your motors are working so hard.
Nearly 60A for a 960 hex is a lot, as we wouldn't use that for an Octo w/payload.
How heavy is the hex?
