That looks like customised firmware, and the flight modes just show as numbers.
I would update to 4.3.3
The compasses dont look detected and calibrated properly.
Go outside, wait for a good GPS 3D Fix then run the compass calibration.
Then in MissionPlanner / Mandatory… / Compass
Check which are internal and external then disable the internal compass
While still in Mandatory Hardware, got to Initial Parameters
Put in your prop size and battery cell count, also select “Suggested settings” , if you have T-Motor Flame or Apha ESCs then select that T-Motor option too.
Accept everything it offers.
Then also set
MOT_SPIN_ARM,0.10 to 0.12
to ensure reliable starting of motors.
When you next arm and fly the Hover thrust will take some time to relearn, so just keep trying to hover in AltHold and it will settle down in time. Then fly around doing lots of yaw and some turns like a figure 8 pattern.
We can check that log with MagFit to improve the compass calibration further.
It was me not understanding your original question properly, so I looked at the video and saw the copter do a full turn.
I dont think you should disable all the compasses - GPS for yaw does not totally replace the compasses.
Compasses are still needed until flying with a good GPS track.
You could enable the compasses and do a flight with some yaw and some circular or figure 8 patterns and we can run it through Magfit to drastically improve the compass calibration.
EDIT: it’s been a while since I read about GPS for yaw, so I’m reading it again to check I’m telling you the right things. I would probably still do the compass cal (via a flight and magfit)
I think you can leave the compasses enabled and still use GPS for Yaw
EK3_SRC1_YAW,2 (GPS only)
or more likely
EK3_SRC1_YAW,3 (GPS with Compass Fallback)
and just disable the compasses for testing purposes.
Probably set EK3_SRC2_YAW,1 for compass only in case there’s no GPS signal or glitches.
I see in the log you are getting Yaw from the GPS units, so the parameters you have seem working OK.
So long as the setup is correct and reception is adequate, a moving baseline configuration absolutely replaces magnetometer based heading. It is the primary solution for large vehicles with lots of interference, and there is potentially more detriment than good in leaving compasses enabled in those cases.
I cant see why this copter does a yaw rotation after launching…
Do you mind having a look at the log?
It seems everything is working with GPS for Yaw. Personally I would enable and calibrate the compasses via magfit and see if the issue remains.
Compasses can always be disabled later if they prove problematic, or the EK3_SRCx_YAW is easily changed.
That’s where a test flight and the magfit utility come in
So potentially you could
Set them up for GPS for Yaw but leave the compasses enabled
Do a test flight with circles and figure 8 pattern and so on
Use magfit to produce updated compass calibration settings
Set EK3_SRC1_YAW,3 (GPS with Compass Fallback)
EDIT: maybe do the large vehicle mag cal first
If you are going to reproduce this copter then make sure the tuning is absolutely near perfect. Looking at it flying (just visually) and saying it’s good enough - is not good enough.
If it is excellent in logs then you can copy the tuning related parameters to a new build (using the same components) and you’ll only need to do one test flight to verify correct operation.
You might need more flights for a burn-in process.
You can also set up your own set of read-only or default parameters.
