I got my Phantom 2 today! The set up and install went pretty smoothly except one thing. One of the props (Grey one) didn't not spin on as smoothly. The threads at the top don't let it go on as smooth. Once it gets past the rough patch it goes on OK. I was going to call DJI but apparently they don't have a tech support number (not that I could find anyway). I was just wondering if you guys think it's a problem. The prop otherwise seems to be working fine. Thanks! If all is well the first flight will be tomorrow!
