Purchased off of ebay, Phantom 2 Vision. Batteries fully charged, calibrated compass, waited to get satellite lock with 7 satellites, green lights flashing, and when I pull the sticks down to the middle, all I get is this when I use the controller to try and fly. My iPhone is binding with the wifi, and I am getting camera signal. If I shut the controller off, I get a warning from the app saying connection lost. Anyways, here is what I get. http://youtu.be/BSm7xy9UjYE Now, when I put it together the first time, I put it together without the prop guards on. I did, however,put the longer screws in required for the prop guards.(The screws were out, so I just put them back in without the prop guards) Did I foul up the motors by putting the longer screws in without the prop guard, whack sent them too far into the motor, and is causing this? Or is this something else? Thanks in advance for any ideas or help?
