Began routing of heater ducting. I've still got some adjusting to do, and will probably switch the outlets for the front and rear ducts from the mixing box. This box came from the Cirrus from which I got my engine. It provides for proportioning the heat between front and rear, and a separate valve for the defroster. I had to change the mounting configuration of the butterfly valve on the defroster outlet to ensure that pulling the cable will open the valve.
The right rear heat outlet is closer to the center of the cabin to ensure clearance from the roll servo.
