Like Matt said, the tunnel is a sucker not a blower ... don't think that's the technical term tho !!

The drag question ... um .. well not sure on that one just yet. For now I want to keep the wind tunnel as simple as poss and try to get it working as consistently as we can so that we can measure downforce with some degree of accuracy from model to model. Thanks for the ebay link, its on my 'watch' list !!

Thanks to everyone for the tips and links, I look at all of them .... it's been a steep learning curve so far and I think the hardest part will be collecting the data and applying it to something useful that can be used positively on track .... again any suggestions are much appreciated !!
Very cool project! I work in the aerodynamics department at Mercedes F1 and have always wanted my own tunnel for RC testing. This one looks superb.

Have you tried using 4 scales (one for each wheel)? That's how most real tunnels work.

What sort of repeatability do you get? This is always the hard part ;-)
