Permitted compass elevation angle

ArduPlane Plane 4.4
1

Hello,

I’d like to ask what angle is permitted to mount the compass in the plane. I’ve read that it should be horizontal but this does not work out in my case.

I currently building an ARWingPro and found out that the intended GPS mount in the rear section has a small elevation angle upwards, so my Holybro M10 GPS+Compass is pointing about 10deg upwards.

I also see problems in the location with the ESC that ~4cm below it, some magnetic cover holders 6-8cm in the area, so I’m evaluation if it’s any good to mount the GPS+Compass in the front where the center camera is supposed to be.

To sum this up, I disabled compass because the EM noise from the stock T-Motor 40A ESC was causing drift. The intended GPS position is not feasible for a compass.

I think a slight incline of 10° or less could be acceptable, but definitely not ideal. Preferably, you’d craft a small wedge to place it level at cruise AOA.

But…as you discovered, it MUST be placed away from high current wiring and other sources of EMF.
