I’ve been playing with various configurations of NACA ducts, extension ducts and electric fans on the DF to add a bit of airflow through the cockpit. The more that I tinkered, the more complicated the cockpit got. So I decided to try to organize the cooling and sort of wrap it all up in a dashboard. The idea was to provide a single piece that surrounded the vent from the NACA duct, incorporated the fans and organized the fan and switching wiring. Here’s what I came up with…
Below you see the plug on the left, made from 1″ pink foam sheet, bondo and paint. The resulting mold is on the right. I should have made a 2-part mold. Extracting the plug and then the part from the mold was very difficult.
The resulting part is on the left. On the right is the backside of the part with the fans and switches installed
This shows how the ducting and dashboard pieces fit together.
