Guys I need help!!!
I don't have access to any airfoil programs but what I'm looking for is this....a flat bottomed Clark Y airfoil that is stretched...I want to design a foam delta wing using a flat bottomed airfoil with the root airfoil at 20" and the tip at 10"...the thickest point in the root airfoil should be no more than 1 1/2 inches.....
Hope someone can help with this.......

Thanks in advance

Your airfoil is 7.5% thick. If you choose a camber value of 1/2 the thickness, you should have something close to a flat bottom. Try a NACA 3307

If you're making a true delta wing, you may want some reflex or else the plane will pitch down. Did you want a drawing of the airfoil? Just PM me and I can give it to you.

PM'ed you but I can post it here as well. This has the DXF, DWG, and BMP of both root and tip. Enjoy and good luck with your plane.
