Navio 2 magnetic field

[RcHexy1991]

Hexcaopter instability due to magnetic field interference. Navio 2 flight controller. Any suggestions?

Care to elaborate? Is this a warning you're getting and wanting to know why? Or are you getting MI and wanting to know what to do about it? "Cuz my first response would be try somewhere else...

Is the compass mounted near an ESC or motor? If you have 4-in-1 ESCs you may need an external compass if you can't add more separation.

I get this warning on ardupilot and the drone kinda goes crazy. It's a tarot hexacopter with a navio flight controller. The power distribution hub is about 4 inches away and is a tarot 6 in 1 power distribution hub.

Yes I want to know why. My drone is very unpredictable and I believe this is why

Could be a bad sensor as well if it is not EMI. I would try the external sensor if possible.

this is a picture of the drone from the top if this helps at all.

Move the sensor out onto the arms if possible.

so move the gps?

Yes, it is probably a GPS/Magnometer combination so moving it away from the ESCs should help.

... Lotsa real estate on THAT bird ! ...

but my ESCs are below the motors which are at the end of the arms. The GPS is not close to the ESCs.

Probably noise on the power lines then.
Does your PDB have filtering ?
In any case I'd slap a low ESR cap in there, say 1000 mf
on the power lines to the GPS/Mag or FC and see if that solves it

this is my PDB. it came with the frame.

Try adding that capacitor and see if that fixes it.
