I was out flying the neighborhood tonight on my third battery and decided to do some very low filming at 20' around a house we bought as an investment property a few weeks ago across the street. Battery got to 30% and I got the typical low battery warning and was setting it down when I got a verbal warning "going to Home in 10 seconds." 3 seconds later while only a foot off the ground, it took off to my GTH height (200') but at 15 feet off the ground hit a telephone cable, flipped over and landed upside down on the lawn. Luckily, only 2 prop guards were broken and the props blackened from contact with the telephone cable. I removed all the guards, replaced the props and inserted a 4th battery and all systems checked out, and it hovered great so I looks like I got off lucky, just like my handle! I thought it didn't head home until power got to 10%. Am I mistaken?? Is this a setting you can change? Thanks.
