Flying in a wind is exactly the same as flying in no wind - if the plane isn't travelling where you want it, make a conventional turn with aileron until it is travelling towards where you want it. It might not be pointing in the exactly the same direction as it is travelling but that's a ground based perception problem. So if the wind is across the runway and the plane is drifting off to one side of the runway, simply make a small conventional turn until the plane is travelling along the direction of the runway. Rudder simply doesn't come into it. No plane in flight will weathervane into wind, it is physically impossible. For a landing in a crosswind, full-size don't like the side loads on the tyres or the destabilising effect of front wheels on taildraggers, so just as it touches down add a bit of rudder away from the wind to yaw it to point along the runway. Don't do it too early or the plane drifts across the runway. For models it is less important. That's the only point in a crosswind landing that you need rudder.
