That's really a very challenging environment for that to fly in - you're braver with yours than I would be with mine !
I think the new Neo's tracking would be much more suitable for this sort of walk as its follow mode prioritises maintaining the same path the walker takes, and thereby would have stayed more behind you, out of obstacles way ! Good test though, and very attractive environment to do it in...
I was going to mention the Neo but as you said it can only track in one dimension, the 4 can do that very well. But the 4 has a 360-degree sensor system, which means that it can track you from anywhere.
Thank you for the compliment.
I know there is a long, very critical, thread on the Mini 5 but I would love a much better all round tracking facility.
It's a cut, I lost it multiple times. Maybe I should have made the real one when it lost us? Not every 15 seconds as I posted, but really every 5 seconds. In a simple environment it works fine, in a complex one its pretty useless.
I posted this one some months ago.
