I fly some of the planes most of the winter, but those that I don't I store in our home (3rd floor) I do make sure that the batteries in those planes are kept fresh. I even bought a Mango Mit to make winter flying more comfortable. Maybe this year I will hook up the big plane to a tow rope and go skiing behind it. Yea!!! Right!!! fall down, lose TX, watch plane go off in the sunset, try to explain to my wife why I didn't bring the plane home. (Look for new home).
