Over the last couple of months I've had an occasional rattle out of my phantom 3. Every single time what came out were pieces of the clips that hold the two halves together. But today I got a new one after a 15 minute flight. Which one do you guys think this one is? Main board screw? GPS maybe? But that one has the tape over the whole thing. Anyway, I'm used to this from phantoms but this one I can't figure out. Hopefully someone who has taken a phantom 3 apart can figure it out.
