Hi,
I have drawing for PIPER PAWNEE,80" wingspan,but there is no drawing for wing.Only type of airfoil is writen(NACA 2412).This is
semi-simetric airfoil and this is all what I know about it.If somebody know something about this airfoil,please inform me.I am intersted about speed(stall speed also),stability,acrobatic possibility and if possible tell me diference between NACA 2412 and CLARK Y
If somebody have idea for some other airfoil for this model,please tell me.

Thanks!
Danijel
