Just an afterthought. I was thinking of settling for a 1 degree washout. Do you think that this will be a reasonable washouot airfoil tip angle or would one prefer a higher degree of washout gradient?
Not having ever seen the planform view, and relying on the drawing of the plane, it looks like the wing is somewhat like an elliptical planform. Elliptical wings stall equally from root to tip. They don't have a tendency to stall from the tip. Your 1 degree of washout should insure that you definitely don't have washin, but very probably isn't needed.
One reason they went to all the trouble to build elliptical was what they get from them without extra effort. Quite a British attitude, by the way.
