unless you have previous nitro experience you are better off waiting for a warm day.....when you are just defying mother nature to run an RC you aren't very knowledgeable about to begin w/ is just asking for hard times...wait until the Outside Air temp is at least 40-45...I usually don't run at all when it's under 50.....and I like the cold air so it's a real bitch when I'm outside on a sunny day and no RCs in my hand......I'll live though
