I know that I'm going to regret getting involved here, but I think some additional information is in order.
Angle of attack is the angle of the center of the camber line [the "camber line" is a line from the trailing edge to the leading edge] relative to the direction the wing is traveling through the air mass. Note that a wing with "0" angle of attack will not produce lift and it makes no difference what the airfoil shape is. On a flat bottom wing like the "Clark-Y" found in many trainers the camber line does not follow the bottom of the wing, it goes from the trailing edge to a bit more than 1/2 way up the leading edge. This airfoil at "0" AOA will appear to be going down hill.
Now how ailerons function is often not understood. They do not "deflect" airflow, what they do is change the shape of the airfoil, and there for the location of the camber line. If we move the aileron down, the camber line at the leading edge stays in the same place, but at the trailing edge it goes down. The shape of the airfoil is now known as under-cambered, the change in the shape of the airfoil combined with the increase in AOA will cause the wing to rise.
Flaps do almost the same thing, in the same way, as ailerons with some exceptions. They continue to produce lift depending on the airfoil shape to about 20- degrees of deflection, after that they rapidly increase drag with very little increase in lift. The reason that this happens is that at the AOA and severe under camber shape the airflow can no longer remain laminar over the flap and "burbles" or stalls. The advantage to this is the extra drag combined with extra lift will allow for very steep and slow approaches, it's also the reason more than 15 degrees of flap is never used for take off.
Now here is the story with flaperons. This is an attempt to combine to two and there are advantages if done carefully. Extra lift can be had, but if the aileron is deflected to the point that the airflow "burbles", the entire wing control surface will be stalled and there will be a tremendous increase in drag on that wing, resulting in an uncontrollable snap. Many combat and aerobatic pilots slave the flaperons to the elevator to tighten loops, or to the rudder to eliminate pitch coupling in knife edge. Experiment with it and have fun, it's the whole reason we do this. .
