Flying today in the backyard, I had a critical failure. At first, I was surprised when the unit tilted a bit out of nowhere, then I realized what was happening. The unit came crashing down onto some shrubbery, and since the legs were up, the camera broke off. I emailed "email@example.com" as per the product documentation, and the email bounced back (checking the website, it states to email "firstname.lastname@example.org", which I proceeded to email instead). All video was lost from the card, so I unfortunately am unable to post that. Let's see how this works out...I was decently pleased with the drone after 5 flights until now. I believe the screen said "5 motor failure", but that was after it dropped out of the sky. I didn't see any birds fly nearby or at it. I had not yet received any battery warnings, and I would guess I still had another 5 minutes before one. 6 doesn't seem better than 4 right now.
