My AE buddy stressed location was critical in getting large volumes of cool air, which I do. RR SNIP 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!
