RE: Winter Flying...
I use one like PHK put up. I have seen people use latex gloves, but that doesn't work well. A transmitter mitt works well. You keep the full feel of it. Mine has a clear screen on it but I don't need it. You shouldn't have to look at the radio.
Be carefull putting your hands in it. You can bump switches easy. Make sure someone is holding the plane till you are totally ready to go!
