Amen!

Ya define the mission, and how fast you think you will go and look at the
list of airfoils used on airplanes of similar speed and mission. That makes
airfoil choice a real choice.

....and then you look at mark langford's web site and pick the aerofoil
according to thickness. ...from the list of excellent aerofoils
developed for the KR2S on his web site. :-)

you dont have to be correct or competent to design an aeroplane.
you stand the chance of designing a damn site better one though if you
are. having experience and attitude sometimes gets you there.
competence can mire you in decisions and see you achieve nothing.

Why is the Wittman W8 tailwind still a standout in the efficiency
