I hope this is not too basic or a repeat of anything. I searched for this topic and didn't find it. I am trying to develop a 1/20th scale A350. I will be modeling the plane to 3d print molds. I can do a winglet no problem, but the winglet shape is what I am having an issue with. The A350 has a pointed rear of the winglet airfoil. I am having trouble getting this shape. I hope that makes sense. Thanks.
