    Flying indoors question

    i have both a phantom 4 and inspire 1. I have been ask to fly inside a large (EMPTY) cathedral which I am really looking forward to. That said I have not flown indoors. My first question is I assume that I should be in atti mode? Also and I know this is a phantom forum, if anyone has experience...
