Thanks, Pat. I had that experience yesterday. When I lost video link, the screen went to Systems Settings to show that the camera link was lost. RTH brought the TH back overhead and lowered the landing gear but stayed up there, hovering. It wasn't until I figured to Return to the flight control screen that I regained control and landed, without video of course. I was worried that it would run down the battery before landing. Whew!The H's lost comm protocol has always been to return to the last known position of the 16, drop gear, hover, and wait in hover until comm link is recovered, and to land upon low battery if link remains lost. This is not a firmware defect, but a lost comm design feature. That you regained control after turning the transmitter back on demonstrated that it functioned normally. A safer way to perform this test is to put the 16 in Pad mode, which terminates the telemetry/flight control link. To resume link just exit Pad mode to avoid booting up the 16 again.
I have 2 questions:
1. Is there some way to regain video link in this situation while flying? I had to rebind the camera to ST16 after landing. I can't imagine that can be done while it's in the air. Can't do the 45-deg tilt to enter bind mode.
2. My video didn't just glitch, it lost communication completely and without warning. I had been hovering some distance out and up, doing a gimbal pan and just adjusted the exposure to get a better view of Mt. Rainier in the distance. Bam, Systems Settings screen. I was a long way from civilization and not as far out as I have been previously with a reliable connection. There was nothing between me and the aircraft (VLOS). Could the trees on either side of me have somehow caused the loss of video connection?
