Here's what I've learned: When the controller announces the aircraft will land in 10 seconds and you are over a big pine tree, you are probably screwed. If you have a little time left in the battery and you think you can make another round--forget about it. It's not that easy to pilot when the drone is hidden behind a tree and the autopilot failsafe is trying to bring it straight down. The return to home feature can become problematic when your takeoff point is under the roof on the patio. And even that's not bad if you don't wait till the battery level is critical to land it. Panic does not help! The good news is it landed upside down and was not damaged at all.
