Here are some pics of the engine cooling duct. I was messing with it so I thought I would post them. The duct is a fiberglass piece the ducts the cooling air from a hole in the firewall behind the cylinder, to a scale opening on the fuse side. I have not cut any holes in the firewall yet and the duct is just set in place to "see how it fits".
The last 2 pics are of the piece cut from the fuse outlet opening. Really gives a good idea of how the honeycomb looks.
