RE: Winter flying
I flew today at about 19*F with a light wind. It was cold on the backs of the hands but warming them with the truck vents works great. The plane ran and flew perfectly. Starts are not a problems at all. I keep the plane inside the truck untill I'm ready to fuel and fly then after tuning it (don't forget it will need to be richened some from warm weather tune) it'll run like a top. The plane starts again just fine after sitting for 20 minutes or so while you warm your fingers. Another thing that is helpful is to have some of those chemical pocket sized hand warmers handy for in between flying and fueling.
