Yesterday I programmed a waypoint mission that took the aircraft about a quarter mile away. I was flying at 200 feet and had constant video loss and loss of link from the controller to the aircraft. I changed antenna position several times but that didn't help. I set up the waypoints with the aircraft powered up but motors off, told it to begin the mission and it gave me a warning that waypoint flight is only available in GPS mode, to which the controller was set. I powered everything down and started over with the same results. I finally put the aircraft into a hover and then I could begin the mission. All of these quirks are very frustrating, especially signal loss at such a close range. I certainly don't anticipate being able to achieve the advertised range.
