Well if 0 celsius is the cut off point I might as well pack this one up til next April. But I'm guessing this one videoed at Bickleton, Washington a year ago was well below the freezing mark judging by the snow. DJI Phantom 3. Seemed to handle the cold just fine.

I did find after getting in the house that I had not charged the remote controller and the batteries were indicating very low. So maybe that was my problem.
If the sun shines tomorrow chances are I'll try it again.
