I already have that top skin riveted on and do not relish the thought climbing to the tail to fabricate / align / install bracket and unit.
the seat belt cables pass through the baggage bulkhead above the elevation of the longerons and do not interfere.
The installations that have been pictured look pretty good to me. Please don't take this as criticism, but I have been flying my RV for about 4.5 years and I dread each time I need to inspect behind the baggage compartment. It is literally a pain the the %&*, neck and stomach. If you are skinny and have long arms you might be ok, but in my opinion I would move those installations as close to the baggage bulkhead as possible, maybe even in front.
Keep in mind that I don't know the requirements for installation, maybe there is some electronic reason to keep them that far back. If that's the case consider the source of this post and ignore it. my 2 cents. By the way, I want one of those gadgets in my plane someday. But I just spent my last 2 cents. take care
Vans sells a AHRS mount for the 7/9 for a Garmin 900 and GRT EFIS system. I put one in mine but later found out I didn't need it for the GRT Sport model. I put the nutplates in for the GRT EFIS. If I upgrade to a Horizon later on - I quess I'm set. If you go this route it's better to do it while building the fuselage because there are a lot of rivets.

Vans part # IF AHRS MOUNT
Jamie,
I will probably put my magtometer in that location. I really don't want it at the wing tip.
As far as I'm aware, Dynon is the only one to combine the AHRS and remote compass, so you need to plan accordingly and can't treat it just like a stand alone AHRS.

Stein,
Wouldn't you have the same problem mounting at the aft bulkhead where the elevator pushrod is swinging as well? I plan to mount the magnetometer up high behind the baggage bulkhead off the top ribs at the top skins like Jamie showed his AHRS unit. But the point is well taken.
Hey Jamie,
Do you have any pictures of how you are running the cables/wires to that unit? I'm curious as to what route you took.
However its really simple.
Pop the inside left inspection plate off of the wing.
Using 4 brass screws mount the adhars to the inside of the inspection plate.
I shimmed it to level with roughly 1/4 inch worth of washers on the inside edge.
I also rivetted a 3/4 angle across the wing bay just behind the inspection plate opening for increased stiffness (piece of cake even after wing closeout, includes rivets through the rib flanges).
Then its just a matter of running wires and tubes.
I've been flying this and the Skyview for about 20 hours now and it works really well, even during rolls.
If I was building a new airplane I'd probably look harder at putting it in the baggage area or somewhere, but for a retrofit this was super.
it is quite a bit more effort to fit with the top skins installed... here i could just reach in with long arms to fit, position, and drill the fabricated assembly to the longerons.
