Oh dear, read the question fellas. An aerofoil, or airfoil, produces lift when ever it has an angle of attack to the relative airflow, the zero lift position is usually at a negative angle of attack (symetrical profiles excepted). It produces lift irrespective of its orientation. And yes the lift vector of a tailplane generally is towards mother earth (unless I'm inverted in a loop). I think the profiles both you guys have are a bit suss.
