airfoils are discussed. I believe KR builders would find it very
interesting.

You can also type in X/Y coordinates to modify a copy of an included
airfoil. Just key over what's there to put in the coordinates for some
airfoil not in Profili and it will render that airfoil.

After thinking about your post, I'm compelled to comment further. Understand
going in that I'm as amateur as one can be, so I don't know what I'm talking
about:
It was mentioned that Roy Marsh's son is an aero engineer and chose 23012 for
Roy's PURPOSE-BUILT KR2S speedster. The magazine art
ACA 23015 NACA 23012
Western PGK-1 Hirondelle NACA 23012 NACA 23012
Wideroe C.5 Polar NACA 23012 NACA 23012

I believe the book you might be thinking of is Ladislao Pazmany's LIGHT AIRPLANE

Maybe not if that sport pilot KR2S only has a 57hp VW, 1 seat, is 28 " wide, and
has dirty cowling and no pants?
