So I'm outside my house and decided to capture the sunrise. I'm up at exactly 400' and filming away. The power drop has been very slow and steady from the high 90's all the way down to 35% - my typical "go home" level but the sun is just about over the horizon. I figured I'd wait a bit longer - maybe until 20% - still lots of margin for safety. At 25% and I get the "go home" warning but I hit ignore. When it hits 20% I've got what I need but I figure I'll do one slow pan around just for effect. Wow. The power starts dropping like the count down on a bomb in a movie. 20... 19... 18... 17. So FAST! What happened to my slow steady power drop like maybe 1% every 30 - 40 seconds or so? YIKES. I figure I might not be able to complete the entire pan. OK time to head down. Slow and calm and steady. Line up over the driveway, back and forth - avoid ring vortex - easy does it. 16... 15... 14... 13. MORE YIKES. At 11% I give up all pretense of calm crank the down lever as hard as possible. About now some ring vortex might be a welcome thing! Only at a point like this do you realize just how **** slow this thing descends and how high 400' really is. I brought that baby down just as fast as it would go. At 5% I'm wondering just how much it would hurt to catch a drone falling from 80' in the air. Probably do as much harm to me as the drone. Somehow at about 5' in the air I had the presence of mind to shut down the recording so I didn't corrupt the video. This thing landed with 0%. It may have actually powered down just as it touched the ground or possibly even from 1" up. Wow. Just. Wow. Too freekin close for me. I've learned my lesson. 35% and land. No exceptions.
