My best storage tip is to keep the model coated with a fresh layer of oil from exhaust residue. Replace the layer frequently throughout the winter months (weekly if possible). The best method of application is by getting the model airborne and using several tanks of fuel. Note that the process may require modification of the landing gear (e.g. installation of skis) depending on your particular climate, and may require copius application of hot coffee or hot chocolate to the pilot.
