If you google "Lift Reserve" you will see many different ways of making or purchasing an angle of attack gauge.
She’ll tell you all you need to know. Nice, honest plane. She won’t bite even when all crossed up. I’m not gonna bother.Quote:

Just my opinion on AOA instrumentation. First, I have one (Dynon) and really like it. Second, it uses an audible beeping sound that gets progressively more intense until it becomes a solid tone at incipient stall. Without the audible tone it would be useless to me. The Dynon also has the multi-colored visual indicator on the panel, but when I am on very short final I have no time to take my eyes from outside and look down at the panel. I guess some folks with visual indicator only are satisfied with it, but I believe most of them have it mounted up on top of the glare shield or in some type of HUD.
I have mine just under the glare shield Jim with no audio, although that option was available. I agree that you don't want to be looking down on short final but in the position just under the glare shield, I have it in my vision when looking at the touch down point. It is very clear to see it going from green to orange and then red. My personal preference is visual over auditory - I don't like audio when flying (don't play music or have phone hooked in when flying) - I think it is a case of what is effective and then training yourself to use the information it provides - same as referencing airspeed indicators f you don't have AOA.

Jim, can you please provide some installation details for your Dynon AOA? Where did you mount it? Can it be installed on a plane that is fully covered? Many thanks.Quote:

The Dynon system integrates with their EFIS, electronic display (glass panel).
I used their double pitot tube that does AOA and airspeed connected to a D180 FlightDEK.
Yup got that. I have a D100. I was wondering if it is possible to install the AOA in a completed aircraft or would the plumbing of the tubes be too difficult.
The hardest part would be mounting the pitot assembly. You may need to do some fabric work.Quote:

No pitot tube and tubes to install. It’s an electro/mechanical system that only requires a set of wires running through the wing from a vane driven sensor to the indicator on the panel. The vane is easily installed by removing a wing tip and installing it so it is outside the prop wash. Mine will be installed about 12 inches from the wingtip.
There is an in-flight calibration procedure.

Thanks Rodney. Please let us know how it works out.

Many thanks Av8r3400!Quote:

when I built my rv I put in the dynon with all the required things. Thing is I never set it up, just use my butt for aoa. same in the kitfox, I find it hard to stall out, just use the butt. my vote would be the dynon. good luck.
Hey Guys, needs some help on this old thread. I installed a CYA-100 AOA vane like Rodney put in his aircraft. Just got it programmed today and works great and very easy to program.
My problem is that The LED indication is not that large and cannot keep in view while trying to do a full stall landing for rough terrain, would like audio warning. It does have output tone when Red LEDs start to come on but I do not have an input in my Comm Radio, only input for music player (flighline 760A). Also using Lightspeed Zulu3 headset.
I suppose I can connect to this input but I would want priority to the stall warning over any other input and I believe the music player has last priority.
Aircraft spruce sell a simple Audio mixer Flight Data Sys AD-60, aircraft spruce P/N 10-03427. Any body know if this would do the job or how to connect it. The CYA-100 doesn't have much info on what the voltage out is or anything. Nor is there much info with the AD-60.
Any help would be appreciated.
