Cool, I did a cal flight in that area this weekend.


Made a new flap setting ring for the ASI. Added an inside piece of tape for the outside pitch string. In flight, added a dot to mark string position for best L/D.

Then checked to see if the center of each flap settings on the ring matched the dot. They did pretty well.

I've been thinking about an electronic AOA for sensing the H&V air direction. I have an Ardinuo and diff transducer rigged to a machined nose piece with a pitot and angled port. It can sense a 1% angle change on the bench with a wind tunnel (some call it a shop vac). But I'm not sure if it would be any better than normal instruments already there.

Your picture shows you also have the pitch string. Have you added the dot and checked to see if the electronics stay's green at different speeds but still on the dot?
