New RV10 Accident Report.

Then all the boxes are different sizes with different hole pattern making stacking a challenge. And then DSubs with screw ends rather than thumb screws are another challenge. All that said, mounting remote components is so much easier than back in the day when everything was so so long they required cutouts in the subpanel.

Dynon, on the certified side, has some trays that fit behind the EFIS. A concept that could be adapted to any brand EFIS and easy enough to roll your own. It adds to the options in the quest to find the "best" location for everything.

I find it curious to see the ADHRS module included in this arrangement. Surely there's a lot of magnetively-attractive metal in that stack. Seems like it would impact mag heading sensing.

I wondered that too. They are probably mandating the remote magnetometer in this application.

I like that tray concept. Looks like it would be fairly easy to build one. Another interesting option is one I have seen others do--install a horizontal tray at the base of the panel, supported between the panel and the middle bulkhead, and hinged so it swings downward. This only gives you one level though, where the tray concept allows stacking.

I also find it curious that it is shown with a single ADHARS. I believe they are certified with a single screen and a single ADHARS with a D10A as a backup. It seems most of our panels these days have dual screens (some with 3) and dual ADHARS and some sort of backup.

I used aluminum angle on the sub-panel to vertically mount several stacked items. In my case, the connections are at the bottom of the devices, but other orientations would work too.

The sub panel fills up quickly of you are doing a lot of remote stuff. There isn't room here for an ignition ECU box.

Bridge a couple of angles from the panel to the first bulkhead and mount your accessories under it or on it. As many have done, you can go the extra step and make it a hinged drop down panel for even easier maintenance access.
Not everything needs to hang on the bulkhead panel. The ECU box does not need maintenance, at least mine doesn't and all of the connectors are visible and easily accessible.

Point taken.

The original mounting scheme I devised for my ECU box was attachment to two pieces of angle stock bridging between the left and center longitudinal ribs that support the sub-panel and panel. It looked great tucked away up there above the rudder cross-tubes. Turns out that access after original installation was a nightmare and the whole reason it's now under the seat pan.

If you have a way to make it work, go for it. My experience may have been tainted by not thinking the problem out well enough, but it was not a pleasant one. The folks who are saying that the sub panel to firewall zone is not a good place to locate things you ever want to see or touch again are in alignment with my own experience. Lying on your back in the foot well of an RV-10 is only slightly less miserable than doing so in an RV-6A. I have both tee shirts.

Am I the only one that thinks this thread has had a major bit of drift??

And a huge amount of speculation based on a news report - not even an NTSB preliminary…..

DR can unlock it if I have been unfair.
