The obstacle avoidance was the big selling point. Three different times I came too close to models I was shooting. A tree is one thing, a human is another. What I'm realizing is that you need to be close to things to get the feeling of motion. It's really hard to judge distance the further the drone is away. The Typhoon H should make it safer to get in close without crashing. I got a great deal on a Q500 4K if anyone is interested?
