Pitts.
You mention shaping the vane. It seems the latest trend is to have a fairly sharp, pointy leading edge.
Many older intakes had a bull nose edge, like the leading edge of an airplane wing. Thoughts?
I’ve really covered my thoughts on this so many times that it’s been throughly discussed. I don’t like sharp edges anywhere. I also provide lots of what I think are good pictures to show the “shaping” that’s is being performed.
