Actually the LEGO company has curiously-tight standards on it's components. The propeller blade in view is actually aerodynaically accurate for what is supposed to be a toy. Mount it on a hobby motor (mabuchi 535, check your local R/C shop), and you will have a powerful and efficient cooling fan for many projects. Only troubvle is paying the exorbitent prices for the kits. Raise your kids on LEGO and you will spawn the next generation of mechanical engineers, I promise...
or buy it of pick a brick

Hehehe... the most basic of toys. We had those when I was growing up but they were made of those plastic popsicle sticks. Good times.... good times....
I don't think that axle in the picture is a 12. There should be like this launcher thing for it. That would be cool.
