I flew my Phantom 2 Vision at -5 degrees yesterday. It worked perfectly. My Samsung Galaxy 3 however, lasted just a few minutes before it froze up. My P2V was also very stable in a 10 MPH wind. Held its position very well as you can see. 
This was taken December 7th, 2013 at sunset in Minnesota area code 952 with a 10 mph west wind.
Burrrrr...
