Bulent,

         Beautiful design! Hope it works as good as it looks.

Thanks Kelly, My thinking for the sloped design was that at full power nose
up, the opening will be more perpendicular to the air flow and max. frontal
area. In level flight,the frontal are will be slightly reduced. Who knows?
That's why they call it experimental aviation :)

       Very interesting Bulent. That is the same reasoning I am using for my
 radiators(one each side)which will be inside the wing strakes behind the
 firewall of my Dyke Delta project. I am using NACA report information that
 involved radiators buried in wings. The report has test results for many
 shapes and sizes of inlets and outlets as to which are most efficient. The
 inlets are on the bottom side of leading edge of the airfoil. The inles are
 most efficient at climb angle of attack and slightly less efficient(also
 lower drag) at cruise.
