Re: Sparrow strainer stall
Since it was built as a pylon racer, the mission was quite different than fast cruise. Not sure, but I think Roncz designed the Amsoil airfoils also. Take a look at the area behind the 50% chord, you will see the camber there, but you are right, it is close to symmetrical.
Cheers,

Looks almost symmetrical! Would perhaps need a bit of up incidence for cruise. But then you're not looking for just cruise when racing!
