Orange cube compass quality

Hi all,

I’m using right now an Orange Cube, and I often encounter problems to correctly calibrate compass, I do this outside without interference sometimes I have to do the calibration during 5 min before to have a correct result. I added an external compass GY271, and with it I have no problem I got a good calibration everytime and everywhere, so why is it so difficult to calibrate and have a good result with internal compass?

Interference from power wiring. This is normal.
Disable the internal compass.

Yes this is what I did, but I think it’s a shame to have a cube that’s quite expensive and not even be able to use the internal compass that comes with it.

Raise the autopilot above the high current wiring. A few inches above the plane or the high current wires can cut interference down significantly.
