Wow, its been hovering around zero degrees for the last couple of weeks. OK, since my daughter was home for Christmas. Today, I went back up to the hangar, turned on the torpedo heater, pointed it at the cabin, and began work. I primarily worked inside putting screws in access panels etc. I also worked on my continuing seat release mechanism. This may be the weakest point in the whole aircraft design. My dog Cinder, tucked in the back seat of the airplane as it got quite warm inside with the heat pooring in. Outside the cabin, it was freezing.
