Sounds like a cool idea, but how would you measure lift? Had a friend do something like this but scaled down alot. He had a wind tunnel he made and had the wing mounted on a scale. He would zero the scale out with the wing on it, and when runnig the wind tunnel the scale would get negetive weight which was his lift. You could do the same thing in an empty room or garage, you'd have a better time controlling variables. Just try to route you exhaust out the house somehow.
