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

Tom
