what is the drag coefficient of the S4?...
0.4?...
Just reading about aerodynamics.. I didn't know that the shape that has the lowest cd is a water droplet; cd of 0.05. What exactly does a water droplet look like as it's falling?.. anyone have a pic? I know when lava explodes from a volcano, it forms a spiral oval..kinda like a twisted football... maybe something like that?

The NACA airfoil 0025 has a Cd=.06 (m)
It is very similar to the water drop, but not quite right. Go to the website I linked, and type 0 0 25 in the Java applet, and it will give you the shape of the airfoil.
