issue with my phantom 3 purchased on ebay. When I attempt to take off no fans spin and I receive a 'command time out' error on the ipad/iphon 6 app when trying to take off. The IMU area is grayed out and no values are showing, RTH times out also and trying to format SD times out, compass collaboration does not do anything when selected, it just says start and nothing. i'm running the latest firmware and everything was updated, I see version numbers but the RC remote says serial number NA. Any ideas what could be causing this? The unit also is displaying a 'safe to fly' message along with having acquired satellites...everything looks good and in good condition, camera works and takes photos fine. I Also get two solid green lights and flashing red.
