Thanks for the info guys! Im a diesel mechanic by trade and I know how diesels run in the cold![:@], Just wasnt sure about the glow engine, the wind chill has got to be a bear up there at 60 mph! just checked the weather again and looks to be 0-6 mph nw wind..........straight down the runway, wish I had 2 sets of batteries now, 1/2 to hour flying tomorrow is just not gonna scratch the itch! oh well, better than nothing.
