RE: Wind tunnel
true, but they have time, money and a nice shop. I do not have any of those. My high school's shop is joke. We have a wind tunnel but it is crap. I could fix it but just wanted to see if I could get one premade to save time.

RE: Wind tunnel
The refrigertor box/cooling fan windtunnels of Mythbusters aren't good enough for anything worthwhile aerodynamically.
And, for anything worthwhile aerodynamically, you'll need a very complex sensitive balance to measure the forces on the test specimen.
Kitchen scales can't do this.
A quality wind tunnel that provides useful takes a lot of bux and time.
Particularly for measuring drag, the numbers are so small that ALL friction/hysteresis errors MUST be removed from the system to get reliable data.
