hey, i flew a mission into a stadium below the top of the bleachers using litchi and it worked fine. and NO, it wasn't an event at a real stadium. it was at my school and there were just some kids prcaticing, so not breaking any faa rules. anyway could you not plan a mission for it so you wouldn't need your controller? i guess gps was fine too since it returned. that's cool though carrying something with your drone. i'll have to try that out!
