I have recently completed a Master's Degree in Engineering. My thesis was on airfoil design and analysis. I have spent several years studying airfoils. It is my opinion that the NACA 23 series is not a good choice for an airplane. Its one good point is a low pitching moment. It has a sharp stall and a drag coefficient that is not particularly good.
