Been flying with an angle of attack indicator in my Cessna 182 for 1500 hrs, love it!
Recently bought a second airplane , a Nanchang CJ 6, first mod I added was an AoA .
Highly recommended, its a safety improvement and no guessing the numbers anymore , Vso, Vx, Vy,Vg , It compensates for weight and temperature, no more floating or sinking, land at the right speed.
