Hey guys. Been reading here a lot a received information before I made my Phantom 2 V+ purchase. Regretfully I am her hoping you can help again with a problem I am having. Received the first Phantom last week. When I started the unit only 3 props spun and the other would spin stop spin stop. I purchased the unit from Amazon so I sent it back and they sent me another one. I received it yesterday. Went to fly it today and same thing. See video http://www.youtube.com/watch?v=-yXR1JfAsRo&feature=youtu.be Now that it has happened twice I am wondering if I am missing something.I did all the updated. Both times I was outdoors with 9 satellites. Any ideas?
