Yo T! What took you so long man? You said its been a week, true but it felt like a month bro. The airfoil concept is amazing as I saw it on BBC sometime ago saying airfoils are basically any "surface" that helps produce lift. Any surface I repeat- like you can make an airfoil out of cardboard paper for a miniature airplane. How cool is that!
