I understand how to calculate the airfoil height. What I need is how to calculate the radius, so I can subtract height to get the sagitta. I hope I'm using that correctly, as I don't recall ever seeing "sagitta" before! I just tried using the spreadsheet you posted, and see that it does calculate both. Thanks!

I don't know what a Simplex airfoil is, or where they are used. Also, it seems a bother to have to scale up an airfoil to its final size. Errors creep in taking measurements and plotting larger versions, and copiers distort, too.

Thanks, Wombat and Ole Bill for your replies! Educational, and useful!
