okay so got my son a P2. set it up before christmas and flew it fine. this morning after we opened gifts it was about 6 degrees F outside with a little fog. tried to fly but it wouldn't. got sat lock and then flew after about 10 seconds got blinking red lights and it just started to drop. could not go up. after it landed there was ice on leading edge of blades. that was funny. waited till sun came out and fog lifted and it was about 16 outside and it flew fine.
