I realized many times at Meljet model, that when you decrease your speed and extend Flaps 10 at 200 kts, a warning sounds came, and stays until 170 kts. But I never had a stall with it at 180 kts with full flaps. I land the bird with full flaps, at 140 kts on the last 2 miles, and it never got stalled :s Maybe the answer is at Phil.
