Cold as in -20 to 20 degrees Fahrenheit. I know the operation settings are for -10 to 50 Celsius. We haven't had a warm day up north here since October, and wont for another month , itching to fly but my Phantom 2 literally flipped out on me the other day. Lights all stopped flashing and it seemed like all gain settings went through the roof - on super manual mode. Lucky it landed in the snow. So I guess no more cold weather flying for me. Anyone else experience this?
