Bad news about the wreck!
Yes, compass error in wind is no fun, on mine the first few recovered GPS quickly but the last one didn't recover until after landing. With a stiff breeze it can move a long way before you notice - tip: don't put your phone/tablet in silent! - mine flew back to me (about 800 feet) in atti all the way pushed by the strong wind. On the plus side, I broke my speed record!
I'm going back out tomorrow to test again, I have 30 days to accept the DJI RMA, or return to seller as faulty.
Regarding wind chill, I don't think that is the problem - apart from blue fingers, but base temperature may be. Tomorrow should be about 3 degrees warmer and flat calm so I'll try the same place.
I've sold my P2V now, so it's all or nothing!
