I have a question which no one seems to have asked. I want to do a low flight around a big cathedral. When I fly the route to establish waypoints, will I lose connectivity as I fly around the far side of the domed roof while setting up the waypoints? I expect machine will then go into return to home feature and have to fly vertically 200 feet to clear the top of the dome. I know once the waypoints are done and I lose connectivity, it will fly the mission regardless. The only solution is to walk around the base of the church as i do the waypoints but this isn't possible with this building. It s St. Joseph's Oratory in Montreal, which is the world's second largest only behind the Vatican.
