Hi everyone! I am certified pilot with 2y experience however tommorow I have job that require flying in the very center of big city where there is a lot of scyscrappers that I need to film (150m and higher). I will start from the platform that is lcoated on 32 floor in one of the building. I am wondering if any of you where operating the drone this way or fly in such crowded area. Any advice? Is there really a high risk of loosing signal because of the interfrence from many antenas, wi-fi and others? Is there any other threats I should take into account before start? I am planing to: - setting RTH attitude as the highest obstacle in the area - do not fly behind the buildings to prevent loosing signal - is the radio signal range dicreased in that kind of areas ? Any tips and advice from experienced pilots are very welcomed Best regards!
