Something weird happened while flying the Phantom. I flew really up high to test its altitude and let it hover for a while. The wind wasn’t too bad (at least on the ground). And when I press down on the rc (joystick stayed down position), right about halfway, the phantom starts to rock or sway up and down in a left right motion. I tried to gain control on the joystick but it just kept coming down and bam, had a crash landing and it tipped upside down. Luckily, nothing major damaged except for 2 split prop guards. Any idea of what could have cause this to happen? This never happened before (without the prop guards). Coincidental perhaps? Another scenario is that the phantom seems to have a mind of its own and it started to ascend uncontrollably. I panicked thinking I’m going to lose her but gladly it stopped and just hovered. I then slowly landed it and that’s when I noticed the busted prop guards. Perhaps the balance with the wind got messed up why it did that. But overall, it was a fun flight.
