Have you seen
http://www.barkeraircraft.com/

The AOA is about halfway down the page. It was featured in one of the aviation mags a number of years ago. Works like the AOA on jets; the vane always points into the relative wind. This one uses a hall effect sensor to transmit to the LED array.

Default LRI

I have an extra Lift Reserve Indicator system I will sell. It includes the part that mounts in place of the outer wing inspection cover and the actual gauge that goes into the panel. You would have to get your own tubing. Send me a PM with your email and I can send you pics and a price.

Mike, If you can't find one.....drop me a PM. I have a unused still in the box with all the hardware. The wing sensor goes in inspection cover under wing. Was going to use it on my Stinson but never did. I'll dig it out and get a price for you.

Default We're Looking for new LRI also

I'd be interested in a new LRI indicator as well if there's one out there. We have one installed and love it, but it has started to stick against the upper limit peg as we decelerate. Looking for a new one that doesn't stick. The website for liftreserve.com is still up, but as you probably know, the lights are on, but nobody's home.

It's an off the shelf gauge; you just need the right pressure range.

There have been several magazine articles over the years on rolling your own.
edit:
Here's a link to an old website article, from the Wayback Machine. Has model numbers for the gauge.

After you purchase the 2-5002, 0-2” of water column gauge, you can unscrew the clear plastic bezel. The needle can be carefully pulled of its shaft, the instrument face removed and replaced with the face from your faulty gauge. You will then be back in business.
