One reason it is working well for him is that the scoop is out far enough
from the surface to be in the free stream velocity.  That far back on the
fuselage the boundary layer is 2"+; so a scoop at the surface, or a
submerged inlet (NACA) would have to have considerably larger opening.

On the Cozy MK-IV the NACA scoop oppening is 3"x16" and is cooling L O-360.
