Has anyone read our heard that when using the waypoints setup in the GO app, does the waypoint "fly first setup" utilize the sonar and vps camera to remember accurate elevation? Will it fly 5' over a landscape or object accurately when pre flown to mark waypoints? I would assume the answer is no, however I'm not sure, given the limited documentation about waypoints. I assume it the waypoint setup only uses GPS for guidance and I don't expect any better than 10' accuracy. I'm curious if anyone has experimented to determine an answer to this.
