I'm looking for airfoil for my WWI replica design, and I want it mostly flat bottom, about 8% and no bad stall characteristics. I found the I.S.A. 571 and it looks pretty good....maybe too good to believe. Please compare the ISA571 & naca 4408.
Airfoil Investigation Database - Showing naca-4408

They are basically the same shape, but the 571 is superior? Is this data right and why the big difference, do you think?
