For years Iwas told "you need a proper airfoil to create lift
Never could figure THAT one out - turns out the fact was simply horse pucky.

Who ever told you that didn't complete the sentence. You can create lift with almost any object if you have enough velocity of air moving over it. However, you must have "THE PROPER AIR FOIL" to create "ENOUGH LIFT" to overcome the effects of gravity on any given object at a given velocity!
