Hi jetblast, I'm glad you got a good result with fillet!

A Planar sections blend should be a good candidate with this too, if it's given more space to work with. I've been trying it over here and it seems to be getting confused right at the trailing edge area though, it might have something to do with the angle of the wing making it think it needs to flip the blend in that spot. I'm going to try and investigate it some more.
