Default ADAHRS

The reason for the question was the need to replace or service the ADAHRS in the future.
I talked to vans yesterday and asked if I could use nutplates and he said yes.
Then I asked about the magnetometer and he said that that could be a problem.
Then I asked about using 6061-T6 aluminum plate and taping holes and he said that should work.

I just might go get some brass nuts and solve the question.

Default SkyView ADAHRS for RV-7A

Can I add nutplates to the Brackets before riveting them to the tailcone.

Thanks
Joe,
I did not use nutplates or platenuts because they're magnetically attractive. Dynon sternly warns about keeping anything ferrous or magnetic outside of a 2 foot bubble.

Here's my homemade ADAHRS shelf, mounted in the roof just behind the baggage compartment wall:

http://www.mykitlog.com/users/displa...g=147364&row=5

I used brass nuts/screws/washers (Ace Hardware) and aluminum adel clamps (Spruce). I had the same concern about accessibility you mentioned. Therefore, before I riveted this shelf in permanently, I cleco'd the top skin into place to see if I could get to the screws/nuts with an angle screwdriver and remove/install the ADAHRS. It wasn't a breeze, but it was reasonably achievable.

Hope it helps.

Default ADAHRS



I don?t think that is possible in a 12 there is steel in all the rivets all around the ADAHRS
I hope it?s to small amount to cause a problem.
Thanks

Default Top Tail Cone Skin

How far off the wall is this approach?

I am about to attach my tail cone without the top most skin installed.

When I do attach the top skin, what if I only rivit it up to about half way, progressing fron the tail forward. With all the static/pitot plumbing in place and wiring in place I could easily lift the skin, mount the ADAHRS, make the connections and finish riveting the top skin.

Workable?

I would think this should work better than crawling in. We did the top skin a couple months ago, and I wish we had waited for the ADAHRS. While there is a little bow in the skin, I would think it could be done, If not, you haven't lost anything, just assume the position...

Default A old Problem in a new light

The Garmin GMU 22 Magnetometer

I talked to Garmin team X and I was told to use non-ferrous nutplates around the GMU 22

I am installing the magnetometer in the wing as they recommend.
The access panel will require nutplates.

Does anyone know a good source for non-ferrous nutplates



See Page http://joesrv12.com/Builder%20Log/bl_15_05.htm

Thanks

Joe D

Just a little advice. Mount the unit on the two ribs first, hook up the harness pitot and static and put a couple of clecos in the fuselage to hold it in place while you pop rivet it in place. Much easier.
