and angle it upwards/inwards. Not sure if anyone else has tried this but
would be interested to hear if they have.
David - I have added eyeball vents to my NACA ducts as you can see in
the following picture pages from my build journal:

As I am not yet flying, I don=99t know how effective this very
non-laminar flow arrangement will be, but I hope at least the eyeballs
will allow whatever airflow comes through to be directed to somewhere
useful.
I seem to recall that there has been some previous discussion here about
finding a low-pressure area for the cabin air exhaust vent, but can=99
t recall details now.
