REFLECTOR: NACA Outlet

[Tony Babb]

My kit came with a moulding that sticks out an inch or so below the
fuselage. It wasn't a NACA duct, just a ramp.

I know a NACA scoop inlet is the best for least resistance for an inlet, I
am wondering what the best way is to have an outlet. I am building the oil
cooler in the nose and making the outlet on the bottom of the fuselage. Is
there a NACA outlet? Is it best to just have a rear facing pipe? Or a hole
in the fuselage that air get pumped out? Does it matter? I would think that
any air flow perturbations would cause drag? Anyone have any thoughts on
this?
