I think you should be winterizing the pilot more than the plane. After-all, the batteries do get hot which makes for anything within earshot of it getting hot..... well, in the winter, that problem goes away.

Keep your batteries charged and hot until they are in the plane and running!!!
Color your bird a different color than the snow!!!
Snow shoes or skis might be in order?!?!
Don't eat yellow snow!!!
Don't fly alone!!!
Snow skis for the plane for landings!!!!
Even if you color your bird a different color than the snow, bring a shovel or you'll have to wait until spring or the first thaw.
