A test after getting the altitude hold with sonar fixed on my arducopter hexa.
I'm flying it in my garden and after switching to alt_hold I don't touch my throttle stick till the end of the video, when I have to land.
You can clearly see that the copter adjusts altitude when flying over a small hedge. It's almost like a terrain following radar !
