Rear wing S821 Aerofoil (designed with advanced aerodynamics)

Hey falks,
I've desided to share what I've designed for my http://grabcad.com/library/jerby car, and thought maybe you can use it in your models as opposite to this stupid square that they have now.

What it does:
- Creates the downforce
- Removes aerooscillations on high speeds
- Improves the aero-stability of the vehicle

Aerodynamical performance:
- Optimised for maximum lift-to-drag ratio
- Best angle of attack is 11-14 degrees, so ! Position it correctly upfront the vector of the wind (If you have something like 15 deg pitch for the back of the car, it has to sit -1 - -4 deg between the wing chord and horisontal line, cos wind current line is actually parallel to the skin of the car and not the ground, see attached picture for explanations)
- Aerofoil S821 SERI optimised for these Reynolds numbers
- Theoretical performance is brilliant (like F1 spoilers)
- Tips are Boeing wing-style (was aimed to try doing it with the same principle at least)

NOTE: It is the push-wing, so it creates a downforce! not the upforce like normal wing

Enjoy

Put some credits if you are using it pls.
