This is a continuation of my efforts to fabricate an AOA indicator. The unit is in and calibrated, and just like one person commented, I find I don't have time to watch the gauge and look outside preparing for landing. Other than that it works fine. In fact the other day taking off heavy and having a really hard time getting the critter to climb, IAS was about 40 when I referenced the LRI indicator for best AOA and climbed out without issue.
