Greetings all. A buddy of mine here in Corpus has asked me a couple of times about wind tunnels, and their use for designing models. Knowing nothing about the topic, I figured i would openit up to y'all.

Has anyone here used a makeshift windtunnel to help perfect a design. It sounds usefull to me. Maybe to determine trim, lift, and basic flight characteristics.

What do you guys think. Usefull, of a waste of time?
