RE: Wing/airfoil design software
No skill needed for the pencil/paper thing, otherwise I couldn't do it...at the size of model you are considering the shape of the foil will make b...all difference. You will notice a small difference in gross shape changes, ie symmetric to curved plate, but nothing much between. Most differences will come from wing plan shape, but then only towards the stall angle. Take up thy pencil, and draw...
