At the moment of liftoff the cross controls should be very close to, or exactly the same, as if you'd just landed in that configuration and speed.

There's a roll input that will allow the plane to lift off and naturally turn slighty into the wind. There's a corrseponding opposite rudder that will keep the a/c tracking straight.

It's one of the small joys, and times to observe your coworker's skill, to do a takeoff that has no side load as the a/c lightens during rotation, and does a nice blended roll into the desired track and control inputs are neutralized.

And this isn't a computer game. The wind isn't always the same during the 10(?) seconds to go from Vr to established in the correct track(heading) and the gear is commanded up. The slight variations in wind, and no one will have the inputs EXACTLY perfect everytime, will take very minor corrections that no passenger, hopefully, ever notices.
