Yes, the NACA 6-series has been very popular with HPV builders, although between the seams, ripples, and vibration, they probably seldom get up to even 20% laminar flow, which makes the shape just a reasonable guess. The Varna is completely done by artist's methods. George sends persistent theorists to argue with me and leave him be, and won't even run a tuft test.
