What if I want my return to home altitude to be more than 20m? That seems very low to me. Say I was flying at 10m and I went around some trees that are 50m tall? That is why I like the way DJI does it and you can set a fixed RTH altitude based on takeoff location. I guess I'll just be extra cautious about losing connection behind tall objects. Let me know if I am getting this functionality wrong.
