Hey,
Lately I started getting a Mini-Z F1 car ready for the Belgian Mini Z cup of 2009. It'll also have to work as a flagship for my R/C tuning company ΠAES (Pi Automotive Engineering Service). For the technical stuff, I got it covered; 3010 FETS, X-Speed motor, full alu/carbon chassis, 2.4Ghz board, etc...

But, the most important factor in F1 is ofcourse aerodynamics. Yes, aerodynamics work on a 1/28 scale racer (just look at the differences in lap times between a Mini Z with f.e. an Enzo body vs. a Mini Z with a Pan body (Schuppe). I downloaded Symlab, which is a CFD (Computational fluid
dynamics) -testing program. But I don't know how to get the full car, a 2005 McLaren MP4/20, on my screen, and how to add/change aero bits. If someone knows how to do it, or if someone would help me, it would be greatly appreciated (+ if you have a company with an online store, I could put your companys name as sponsor on the car).

As said, help would be very much appreciated!

The difference in performance between several bodies does not come from aerodynamics. It comes from weight distribution and body weight.

These little 'Z'-s are state of the art, but with max 40 km/h and an undertray which is not flat, there not much aerodynamics about it.

Just test for your self ... add 5 grams weight to the back, the front or the center and you'll see.
