The instructions are to keep it as far as feasible, practical, from any iron. I take that to mean somewhere aft of the main spar. What is a good location?
I used the boyscout compass method of checking out locations in my OneX - I was surprised at how much the brake-cables swung the needle! I couldn’t get comfortable with any location forward of the back of the seat. I’m still building but planning on putting it near the tail to also keep it from anything I might but in baggage that can mess it up also.

Welcome aboard Fred. I’m thinking somewhere in the turtle deck. Since I’m starting on the td, I figured this would be the time to address any access issues.
Also keep it a good distance away from current carrying wires. I was going to try to put mine behind the panel but with how my power wires were run when I did a quick test I could swing the heading 10 deg with a 4A load.

I built a little rack that mounts the magnetometer to the spline in the inside at the top of the turtledeck. Waiex originally conventional gear.
let you know how it works out shortly. Seemed like the best spot, there isn’t anything else around. Designed the rack to keep it more or less level in pitch and roll at cruise.

Good to see you aboard Gordon. My thoughts are to make a rack to fit between the upper aft fuselage longerons between verticals #3 and #4. Of course this would necessitate some sort of access panel.
Access, at least in the Waiex, is through the control mixer access hatch in the bottom. I’m not sure that cutting into the fuselage skins without analysis would be advised. Or a skinny kid on a board laid across the fuselage crossmembers, via the baggage “triangle”.
now you have me thinking…I installed mine during the build, with the bottom skin off. Not entirely sure that it is accessible with that skin installed. Hmmmm.
Obviously, they don’t need much maintenance.
Update…. Despite the fact that I’m an American of the Male persuasion, I read the instructions…..again.
It was what one would expect…..Until “If you start with a large error, perhaps 15º or
larger, you have little chance of calibrating this error out. Rather find a better location.
In extreme cases, consider locating the SP-6 outside the fuselage, perhaps in a wing tip. The wires running to the SP-6 can be lengthened if required”
bold added.
And my mind immediately went to…. On the top of the vertical stabilizer. Make a wedge tail, like a Spark Vark or Growler.
I’m channeling my inner Walter Mitty pretty strongly today.
