Airfoils to Go! was our first product, released in 1991, and it is still popular today. It has 48 of the most popular R/C soaring airfoils, that are plotted in chord lengths from 6 inches to 13 inches. These plots can be photocopied and used as templates for cutting wing ribs, or to make templates for cutting foam wings. The airfoils can be used for reference and comparison purposes, or just as a "shopping catalog" to find an airfoil that is suitable for your next building project. In addition, there are pre-sorted database tables that list the airfoils included in order by thickness, and by camber. You can quickly look up the basic "specs" for an airfoil, and compare it to the others. The 8 1/2 x 14 book is comb bound, to open easily, and lay flat for easy reference.
