He He you found my video of my boomer, yes it is fun in winter times, temperature usually no problems, I set the limit to -15 degres due to plastic details, engine and fuel system no problems. Engine runs better with moore power in the cold conditions. Cover inlets on the bottom side of fuselage due to light snow can suck into the fuselage. Use ducktape to cover wheel wells for landinggear to prevent this.
Use big skies that are well fastened due to the speed.
God luck
