Thanks, Jerry. Turns out the black guide pin was broken off and inside the camera mount, so I disassembled everything, retrieved the pin, super-glued it back on, reassembled everything, and I'm good to go. Off to the park to fly!
My Phantom 2 Vision just arrived and it appears to have a broken camera mount; the camera is dangling loosely from one side (see image). Can this be easily repaired or should I just exchange for a new one? Thanks.
