D J Clark wrote a guest post for News Shooter in which he reviews the DJI Phantom 2 Vision+ drone and he states, that the device is pretty great however there was one serious problem - at one point his Phantom 2 seemingly fell out of the sky for no reason. According to D J the problem was caused by the Vortex Ring State – an issue with the stability of multirotors. And such situations can be serious. Not only because your hardware can get damaged, but just imagine what could happen if your drone fell out from the sky and would land on a road or a highway. Let's hope DJI will manage this issue and according to D J Clark the new firmware probably gets rid of this problem because the descent speed is now restricted. So if you are using this drone make sure to update your firmware to avoid such situations.
As you will see in the video review, in general the Phantom met D J's expectations (of course aside from the problem above), however he has some remarks:
"The video from the Vision+ isn’t as good as a GoPro Hero3+ but is so unique that everyone I have showed it to has missed its flaws while marveling at the smooth movements. The still images, once edited, are amazing.
The crash was disappointing as I still had another five flights planned. It was also an important reminder of the potential dangers of flying – especially when above people.
As I say in the video the shots above with the Phantom were done at the end of a network TV shoot I was on. I won’t get to edit the TV package for another couple of weeks and only then will be able to decide whether I can sneak one or two shots from the Vision+ in. It may be a stretch. But for online only, and learning to fly and shoot, I would recommend the Vision+. I am hoping DJI come out with a better camera or a better way to integrate the GoPro soon."
