Dana it shouldn't be hard to find out with a quick search of the NACA
database and review of test conditions. They are usually quite thorough and
who knows the airfoil in question may just have some merit for those that
have specific missions in mind for their particular project. (i.e. top speed
or short field capabilities) May be well worth the effort checking this one
out. Had it not been for you guys putting up the money and time in testing
the AS series airfoil most would still be operating with the antiquated
RAF48 version.
