As you may have seen I saved 5#12 oz and created a gaping hole (3 1/8 hole) in my instrument panel after removing my DG.
Unacceptable: Must fill that hole.

Found an Angle of Attack indicator (AOA) I could afford and did not require wires to install, and thus was within my realm.

A close up of the instrument. Note plastic cover on gauge face, as I wasn't sure it would work until post test flight.

Required 2 hoses to new AOA pitot. I elected to route within the same rib lightening hole after ensuring no interference with aileron push rod controls.
The material used to protect the hoses from chafing and potentially leaks was purchased from wirecare.com https://www.wirecare.com/category/braided-sleeving/heavy-duty/f6-heavy-duty/f6h0-75bk-f6-heavy-duty-3-4-black-10-ft-cuts

Was this really necessary? Not sure. After cutting the hoses to length, they are really resistant to slicing. I simply felt good about it.
Also a suggestion from a previous post from rv7charlie (thank you)

I used an electrician's wire snake to fish it though from the cockpit side. Neat trick.

This is the AOA pitot. I really like that the kit came with everything needed, including a remove before flight cover, and instrument hole adapter.

I had a question about the installation and calibration, and e-mailed the site. The owner called me back within 1 day and was helpful and kind.

I've flight tested it and like it.
Easy to integrate into my approach.

I've got the one that Sam has in my Jodel and really don't use it at all. The location on my panel might have something to do with it. Unless it's right at the top, where it can be seen at a quick glance, it's simply too far away and too far inside at the moments where it really matters (short final or serious G-pulling).

Curious to learn what your experiences will be with it.
