I'm running 16.09 with an external mag on a mast. No interference afaict, works flawlessly under load (green/0-3% under full throttle).

If I have the Revo set for Complementary everything works fine. As soon as I switch to INS13 or INS13Indoors the horizon starts flipping. Restore complimentary, things go back to normal.

I've recalibrated everything numerous times.

(On a tablet, I'll post the config once I get on a real computer)

Make foto of inside(mag placed wrong ?), Also test mag with a other magnet see if it's reacts like crazy ( I had one that work like it was on but with no effect -/+ 1 or 3 change)

Also on your photo I believe to see a av TX with no antenna and your battery connected ( DONT !!!!)

Flipping horizon is usually bad orientation of external magnetometer (AuxMag) in your screenshot you have Aux Mag Orientation (Pitch = 0, Roll =0, Yaw = 0), this is only true for OP GPSv9.
Other GPS may have different orientation and you need to adjust these values by +-45,90,180 degrees, depending on your GPS. Values in the bars should be very close to zero. You should see on scope that both AuxMag and Internal Mag respond the same when copter is rotated and values for orientations set correctly.

If your Mag orientation does not match what accelerometers measures, EKF will go crazy and you will see horizon going crazy or even flipping up-side-down.

All good, I had the TX unplugged from the battery (as well as the gimbal) so things wouldn't waste power / over heat. It's partly why there's a mess of wires hehe.

Hrm, let me look into this. I just saw a LP tutorial video on this as well.

I think I got it working (or close enough). Roll 180, Pitch 0, Yaw 180

[Mateusz]

Looks good;)

[drmeatball]

Hrm, needs some more work. Immediately crashed. TY for the help tho!

Always get it flying well without GPS, using Attitude mode and Basic AttitudeEstimationAlgorithm before advancing to using GPS.

The GPS needs this stuff to work right, and if you have a problem, you won't know whether to blame GPS/mag or other stuff.

Please correct me if I am wrong. but isn't Roll 180, Pitch 0, Yaw 180 = Roll 0, Pitch 180, Yaw 0?

Thanks

[DocHardinger]

Yes thats correct :-)

[drmeatball]

Thanks everyone for the help, got it going [mostly] pretty well!

When I switch to a GPS Assisted mode, the hex seems to hop a lot, about once every second. I'll see if I can take a better video (this time of the drone itself rather than from the drone camera), but basically side to side position hold is fine, up and down isn't. Is this a 'put foam on the barometer' thing?

SS of barometer scope. Sitting perfectly still on a table top and it's been on for about 10min.

Better select the altitude (m) in scope instead of pressure.

The altitude should still within 1m at least, this is a unfiltered value.
Be sure the pressure sensor is protected from light. (box, opaque cover)
