REFLECTOR: NACA scoops

[Keith Hallsten]

Noel,

I would advise getting the pre-molded "runner" expansion ducts that will
attach to the back of the scoops.  That way you will know exactly the size
and shape you are aiming for.  I didn't do this on my XL, and today I was
working on filling the transition to provide for smooth airflow (which is
pretty critical in the throat of the NACA scoops).  My kit came with the old
armpit scoops, so I had to cut the roof to create the NACA scoops, too.
Don't actually attach the "runners" to the scoop at the firewall until you
can fit them to the engine plenum.

On an downdraft standard fusalage, how deep are the NACA's?
I've got cut lines drawn on the top, but I can't find
instructions on how deep do I make them drop down.
My kit it old enough that I didn't get the premolded
inserts.
