Hi All,

I am in the process of designing a Pitts Model 14. The documentation lists the airfoil as a NACA 23012 but searching around the net on this airfoil has me a little scared of using it on a 1/4 scale project (~65" wingspan). I've only ever designed mono wing aerobats using NACA 00** airfoils in the past. Should I stick to those or go with the 23012?

Also, the airplane's original documentation shows the bottow wing with dihedral. However, the actual build thread photos on steenaero's website show the wing without dihedral. Which way should I go with that?

Thanks!

John
