AA-Ron had a great idea and several folks expanded on the idea. I wanted to move the fans onto the upper trunk deck and have the intakes in the cubby. I posted the idea on AA-Rons thread but did not want to kibutz his thread and his great idea, so I'm starting a new thread to show how I used sheetmetal ducting to bring fresh air into the cubby through fans mounted on the upper trunk deck, then routed down to the lower aft cabin wall to transition plenums and into the cockpit following AA-Ron's ducting and leading into the footbox. With 45 years of aircraft maintenace and a well stocked tool supply (box brake, stomp shear, and every aircraft sheetmental hand tool imaginable), it was easier for me to use .020 2024T3 aluminum and do what I do!
