This is a project I did for college about 4 years ago. I tested different wings with actual airfoil shapes. I used a RC10L3 with a Monte Carlo body. I wanted to compare an airfoil shaped wing with the standard wing used in oval racing. I wanted to see if I could get a much more efficient wing (lower drag with the same downforce). I have posted some of my pics and data here. I have a full written report in PDF format that is posted on the page.
