Hi everyone, I was just wondering - is there anything wrong with taking off at one altitude (say, a 10-storey rooftop), and landing at another (say, the ground floor level of the building)? I have an idea for a video I want to film and it would involve doing this. I'm just wondering if anyone can foresee any problems with this (since I suppose at takeoff, it would be at "0 meters", but then... would it go negative when I land on the ground? Also, is it unadvisable to perform a takeoff while holding the drone in your hands? (Perhaps the best way would be to have someone else start the rotors, and have my two hands holding both legs?) Let me know if you think either ideas are a recipe for disaster!
