Looks like lows gains to me too from the video.

I'd go with a 99.9% chance of this. I think my Wookong settings are around 165% for pitch and roll, and that's on a big X8.

I've discovered that during initial flight testing, putting a rate adjustment on one of the knobs is a lifesaver. Instant feedback vs having to run back and forth to a laptop. Once one is tuned, set it to the next variable and continue until it feels right.

The next warm day I will try these gain settings. Never had them that high.

I was told on another thread that my GPS Z axis should be -20. Is that right?

Those measurements depend entirely on where your GPS is mounted, unless there's some glitch, trick or error in the software that I'm not aware of. I use actual measurements with no problems.

How do you measure for the GPS and IMU?

You need to find your centre of gravity and take measurements from there to your IMU and GPS. Do a YouTube search for how to do this as it's easier to understand watching someone do it than being described.

People need to use the search feature a bit, i think i posted this 20+ times in like 1 month... :)

For A2: 145/145/150 for Basic and 135/135/140 for ATTI

OP you really need to read the manual too. Almost all the information you want is in there as to how to setup your FC, how to measure, etc. Asking such a basic question is worrisome since we don't know what else you missed/not aware of, which could be the difference between success or a bad day. If still unsure, then ask away, this community rocks!

I gad the same behaviour with my S900 when flying without payload.
With 1.5kg payload and same settings the 'wobble effect' disappeared completely.
