I bought my Dynon for the attitude display and everything else was gravy. It wasn't until after I was flying with it I even realized that it have the AOA option. Being a builder oh and cheap too, I though $200 was a lot to pay so I looked into Dynon's and other AOA devices. Well anyway I made my own probe, cost nothing time about an hour or so and I can report it works great. Attached are a couple of pictures of the installation. The trick to ease of fabrication is that I used copper tubing, easier to solder together. The pitot tube is at a right angle to the support tube and the additional tube is angled 45 degrees down. To hold it I made a slot in the circular piece of 1/8 inch aluminum, I used my mill but it can be done with a drill and careful file work.. Mine as a snug fit to which I added epoxy. By the way don't start on how that copper is going to corrode with the aluminum I keep my plane inside and dry and I haven't seen any at other interfaces in the past year.
