The Wright stuff wing is pretty simple, and the heavy weight limits efficiency. I would look at a simple segment of a circle, with 6% thickness. I doubt there is much to be gained with a simplex in this configuration. I suppose you could try it, at 6%.

You will find a lot more potential in running the rubber, prop, c.g., and incidence.

I am helping my son for his Wright Stuff. I downloaded the lsim34.exe tool from this forum. The wing dimension for Wright Stuff this year is: 70mm wing chord and 350mm wing span. How to design the simplex shape to achieve the best efficiency? The tool only asks for 2 inputs: one is the thickness and the other is wing chord. Could anyone give me some suggestion that how to design the simplex shape to achieve the best wing efficiency?

Thanks
