I bought my Phantom 3 Professional the week that it came out back in the beginning of the year. When I heard about the stress crack thing I made it a habit of checking my phantom before and after each flight. The weird thing is they weren't there after my last flight and I went to check before I flew it today and there is a crack on the front right arm. So it just randomly cracked or they were there but not visible and the recent cold that came to southern California made the crack more visible. I have never crashed this bird or even had a prop strike with anything other than bugs. For those of you that have sent your Phantoms back to DJI lately in Los Angeles, what has the turn around time been like?
