Looks like it might be a good system for someone , but I don't have anymore room in my panel for an AOA indicator ?
Replacement parts ? The last time I used an AOA indicator was coming aboard the USS Lexington in my trusty TA-4J . Right now I have 4 x-checks that I use in my S-18 for AS indications...
1. P/S Airspeed indicator.
2. X-check with GPS ground speed.
3. X-check with Tru Trak Gemini PFD.
4. Good old seat of the pants flying . Power, pitch , airspeed and the sound of the aircraft .
After a certain amount of flight hours in a particular aircraft you know where to place the throttle to maintain a certain AS in a given configuration w/o even looking at the AS indicator . Just my 2 cents after 40 years .
