Without wishing to interrupt the physics of aerodynamic theory, worthy as it is and ever-informative to my simple mind, has anyone mentioned the oft-forgotten technique during crosswind take-offs of .........looking out of the window??? As the mainwheels have left the ground I have relaxed all pressure from the rudder pedals I had required for the take-off roll, allowing the required weathercocking, and (not forgetting the glance at the PFD during rotation) am watching intently over the glareshield for my lateral clues as to how much control wheel movement of aileron is required to be maintained or even increased. And I concur with Rainboe; it's usually a LOT in the first fifty feet which surprises those who have not experienced it that often.
