Yeager is known for being grumpy, and I don't think most of us can expect to have his level of situational awareness. But if you can't fly a light airplane safely without an airspeed indicator, or an AOA indicator, then you need better training or perhaps you should take up golf.

Wow... just wow...

Thanks for the link. That is totally everybody's grandpa, at least mine. When I get there, I hope you'll understand my "grumpy" humor.
I actually had the chance to fly my grandfather in later years around his home town in a C152 shortly after I got my private (more than a couple decades ago). It was an amazing experience for both of us. He trained a huge swath of Naval aviators out of Corpus Christi. He flew the airplane like he hadn't missed a beat. Good times. RIP Annon. (aka. "grandpa' Card")

+1 to Scott in regards to flying a GA light plane with no instrumentation at all. Piece of cake and everyone should be able to do it.

Silly me...
A couple of days into learning 3d modeling, I was just proud to turn a couple feet of weed eater line into a tangible thing.
We've all got very strong opinions on lots of stuff -- I think in large part it's what drives us here and makes this forum work so well...but geez, whether or not you think AOA is useful information or not is pretty much irrelevant to my original post.
Maybe someone doesn't give a poo about AOA but they'll look at the model and think..."Wow, I could get one of those 3d gizmos and build that thingamadoohickey I've been designing in my head all these years."
That was really my reason for sharing. I really doubt if I could build an airplane, or at least not in any remotely timely manner, but those of you much more skilled than me might find the 3d printing world to be much more useful than just a something for arts and crafts.

Thanks for posting about the project. It is great to see the innovative uses of 3D printers. Really appreciate your efforts.

Precision
It's not about being able to fly an airplane, its about flying with greater precision. All of your V speeds are basically indirect/surrogate measures of AOA. Why wait for a sluggish airspeed indicator to tell you what the wing is doing when you can go to a specific AOA and get there immediately? You may wish you had that little extra time when departing a short grass strip on a hot day at max weight with trees at the end.
The problem is that for an instrument to be really useful it should read out degrees AOA. Many of the AOA instruments I see available for our aircraft are just glorified stall warners.
I heartily applaud this effort. The challenge will be to get the vane out in clean air. This usually involves mounting it on a boom ahead of the leading edge out on the wing tip.
Keep us informed of your progress.
