Hi...I haven't flown my H much since last update because of compass calibration issues, but yesterday I was trying again and while I had it hovering in front of me I switched on the Obstacle avoidance . I haven't played with it since I bought the H months ago. As I walked toward the H I got a vibration on the st16 and an arc on the screen showing what I believed was the meters away from it. I recall that the H used to fly backwards as you approached it, has this changed or was I in the wrong mode. I was in angle mode when I tried this.
