My pattern bud corrects for a crosswind as Harry C and others stated, yawing briefly with rudder into the crosswind, then neutralizing to hold the ground track with wings level. If one were to continue holding rudder, the plane would continue yawing. Consider holding an upline or downline in a crosswind; you don't continuously hold rudder, as it would change heading.


I fly full-scale also and we use the crab-n-kick method with low-wing birds like Citation biz jets that have very little wingtip clearance; wings level and crabbed to offset the crosswind (not holding rudder there), then kick the nose straight during the flare just prior to the mains touching.
I don't consider it a detriment flying FS, in fact there's transference between both RC and FS, each informs the other.
