When your drone revolts and takes a stroll south of Half Moon Bay, Ca. I had zero control. The App said it was safe to fly, so I did -- DUMB. I forgot to calibrate the compass after shipping it 2300 miles, then reassembled the landing gear, which houses the compass. I didn't know this until I got home, but somehow the video was on the entire time as I scrambled to find it and get it back. I couldn't see it, as I was atop the cliffs. Just prior to loosing control, the altitude said -15 ft! The sea cliffs are at least 100' tall. Why it didn't hit the cliff is a mystery. Then, it took off on a tour of the sea caves I didn't know where there.
Eventually, after restarting the App twice, I somehow persuaded it to return home. It wouldn't auto-land, it just hovered above me. It wouldn't stay in one place, drifting downwards all the time, but never landing. Landing manually was difficult, as it didn't sense the ground, and resisted my efforts. I saw a pile of weeds, and did a Hawaii-style landing there
