Thanks for the followup.
I own a KF2 that I have not yet flown. I have to get that pesky license thing first. Your original post intrigued me and I did some searching. I had seen AOA devices in a number of videos I have watched. Being a aspiring pilot I wondered if it was advantageous. Everything I found indicated it is a desirable addition. I look forward to your final finding and impression/recommendation.
