I believe the "female" version of the Long eze uses a NACA duct for it's intake and cooling air intake. By "female" I mean the version with the flush intakes rather than the plans suggested "P51" intake between the main gear legs. Most of the "eze's" I seen seem to be using the flush version. Find an eze and have a look.
