120mm EDF fan

My other hobby is flying RC airplanes, and in one of the many RC forums, there was a huge debate pertaining to a certain electric ducted fan. The fan had a pretty severe angle of attack at the tip, which brought folks to think it would be slow. In an attempt to explain how you design a fan blade, I decided to illustrate it by creating a 120mm ducted fan that is designed to travel through the air (in an RC airplane) at 150 mph while spinning at 45000 rpm. This is the result. It came out so nice, I thought I'd share it.
