AOA vs stall warning

It seems redundant to have both.

I plan to fly IFR so I will get the heated Dynon probe. Since I can get one with an AOA sensor, why would i bother building the Van's stall warning.

Any thoughts?
 
I installed it because the leading edge already came with a the hole in it. I tied it to a light on the panel as a backup.
 
There's no need for both, unless you just insist on both a belt AND suspenders like Justin Wilson. I omitted the stall warning vane. I installed the heated AOA/Pitot tube for my Skyview, and closed the stall sensor hole in my wing with micro, sanded it smooth. Like it was never there.

+1. The audio feed from the Dynon AOA is superb.

As others have stated, I didn't install the stall vane since I planned from the start to use an AoA system. I filled the two leading edge holes with NAS1097 rivets and sanded until they disappeared, and the access panel got riveted in place permanently.
 
I installed the stall warning vane (one-bit digital angle of attack sensor) as a backup to whatever other angle of attack system I choose when I plan the avionics.
 
I adjusted the Van's light to come on at 10 kts, and the AOA audio to beep at 5 kts above stall. I wanted both as most of my time and been rotary wing so never had to worry about stall, at least not at low speed.
