For setting my plane up for winter flying last year I jumped up the battery to 2000 mah (make sure you recheck balance as they are heavier) because they will drain faster in the cold, switched my glow plug from an 8 to an A3 and retuned the engine. You'll find the plane a bit more responsive as the air is a lot denser. I did fly with skies last year but had to stick to packed snow. I have just built a set of floats so I can fly off of any type of snow this season.
