ONLY if the speed or direction of the crosswind is changing and only for the duration of time it takes for the airplane to weathercock (fraction of a second for an rc plane) to the new heading to maintain the original groundtrack.

Kinda like speed stated, just tickling the rudder at the right moments to keep the desired ground track while looking smooth for the judges during R/C competition IMAC or pattern flying, not 3D flying for those that obviously don't know the difference as indicated in earlier posts, and again the dreaded ever so gentle stick pressure of crossing up of the ailerons against the rudder with these type of airplanes that does keep the wings level through it all. I know, this is a beginners forum and one should never attempt to cross the controls, or high alpha roll, or learn something outside the box... Its just wrong!!!! Much safer to fly in circles and hold your breath until the moment of touchdown.
