Now I know Abu will not like this

...........but that was my thinking to cheat the tip to make it look scale, while using a more ''flyable'' airfoil for the majority of the wing.
I'm just not convinced that the Clark-Y "flies" any better than the sort of thick airfoil used on the DVI, DrI, and DVII. But at the same time, I don't think the original airfoils looked significantly different from the Clark-Y, so as I've said all along, I think the Clark-Y looks fine for these later Fokkers. And, yes, modifying the tips is a must...and easy to do as well.
