Do a quick explanation sketch Bud.
Played with this a bit more today by adding an additional belly vent aft of the
curtis valves; then another pair of vents just below the leading edge of the
Hstab; then added a passage through the D panel.
The top mounted exit vent provides the most volume flow through the entry vents
into the cabin. However eliminating both top and belly exit vents and retaining
the D panel port and rear exit vents provides a more uniform flow and less
disturbance to exterior free stream air upon exit.
The model being tested has the flap bar slots blocked off; there would normally
be air exiting or entering from this area; which is possibly where CO is getting
in from prop swirl turbulence.
