New ADAHRS/Magnetometer brackets for RV-7/9/10 builders

[snoop9erdog]

Can this bracket be utilized in the wing with the GMU-11?

Hi Van's & folks, This mount is being shipped with steel rivets that cannot be used near the gmu 22 or gmu 11 or likely other magnetometers. Need to get Van's to ship it with alum rivets.

Our experience, such as with the RV-12, is that the small amount of ferrous metal that remains inside the pulled/blind rivets after the steel mandrel has been pulled and removed has not been an issue, and the GMU units have worked fine when mounted this way. That said, if you wish to use a different rivet you may of course choose to do so.

Any Thoughts?

The new ADAHRS mounting brackets already have mounting holes for the Garmin GMU-22, GMU-11 and the Dynon SV-ADAHRS-200.

Just bolt the GMU-22 to the bottom face of the new bracket with the connector up thought the existing hole.

The photograph of the F-00149 in the OP-60 document is an early prototype unit, the parts being shipped are as shown in Figures 1 & 2.

I'm actually replacing my homebrewed -10 mount with one of these.

I get the part isn't symmetrical and is made to go more towards the port side.
Has anyone had any luck trimming the top of one of the tabs and placing it in the middle section?

How about possibly using non-ferrous hardware like brass and dropping in my case the GMU-11 down about 6"? My main concern is the length of my harness not reaching the new mount.

This might be more work than it is worth. It is relatively small and short. If I were considering a center mount with this I would look into using two. I haven't even though about it but that is what popped into my head.

Here is a picture installed in my -7. There are holes in each leg(tab) that are large considering the size of the part itself.
Something to consider, they are inexpensive.

To add to that, the GMU 11 is shipped with steel mounting screws. I suspect they would have used brass if that was a problem.

I actually think you're right. I'll mount it in a similar spot and see if I can successfully reach it with my existing harness. If not I 'll make some extensions out of aluminum tubing or something and drop it below the bracket.

Received the part today, was looking forward to some construction... but it only took me about 10 mins to remove the bluing, cut the tabs and deburr the part.

Update: Didn't realize this mounts essentially on the first frame behind the baggage bulkhead. Won't work for me because of my AC unit. Went back to my old homebrew part.

I like it. I'll buy one... ok, now how about a yaw servo install kit for the 10?

You can use the one from Garmin, or the -14 one from Vans.
