I am a commercial photographer for a living and one of my clients is a casino. When I told them that I had a drone they asked if it was possible to do some aerial video on the gaming floor. This will be when they are not open so flying over people isn't an issue, but I am assuming that both the GPS and compass will be inactive indoors and I was wondering if anyone here has some experience in these conditions so they could tell me how stable the P2V would be flying indoors. Thanks
