How do you know they were at full deflection, did you run into the cockpit and brought up the flight control page on the lower ECAM (full deflection is +/- 25 degrees)The ailerons were at full deflection from taxi through takeoff until the point of rotation.
Take off and rotation is flown just like a normal steam driven aircraft, but immediatley after you get airborne the flight mode is progressively blended in, and then you have one of the nicest A/C's ever built (at least the -330), it makes the 757/767 look like a pile $hit.
