I contend that if your attemptig to land the wings are keept Level with the ailerons and the heading is done with the RUDDER.
Full scale pilots don't fly that way. Why should we? Except when you are doing a slip intentionally, there's no reason why either a full scale plane or a model should be uncoordinated
Is that a side slip or a forward slip? Big difference between the two.
As to what full scale pilots do, it depends on the airplane what technique they use. While dipping a wing into a cross wind and touching down on one wheel works nice on a little Cessna, it tends to bend metal on a 747.
