SNIP jim, I haven't had Vinces problem on my HR2. My AE buddy stressed
location was
critical in getting large volumes of cool air, which I do.

Rob and others,
I certainly don't dispute that the wingroot vents get plenty of air.
They do. So do the NACA vents on the fuselage sides. However, both of
those locations are 10+ degrees F hotter than the NACA scoop under the
wing. 10 degrees doesn't sound like much, but when it's already 85F and
90% humidity, it is miserable.
Having just returned from vacation and a cross country drive from Los
Angeles to Indiana, via Death Valley where it was a comfortable 110F and
<10% humidity, I think I can safely assume that it is the humidity that
makes Indiana and Kentucky uncomfortable compared to anywhere in the
western U.S. or Canada. It gets blazing hot out west, but without the
humidity, it's nowhere near as uncomfortable as it gets here.
My whole point here is that the underwing NACA scoops are measurably
cooler... so why not enjoy the cooler air instead of the hot fuselage
air if you're making a change or building anew. It's a mistake that I
won't make again!
