Without meaning to sound patronizing, every Piper and Cessna (at least) that I have flown requires INTO turn aileron during the turn, due to a little phenomenon called positive static lateral stability.
Without meaning to sound patronizing, if you'd used the rudder to avoid slipping out of the turn and keep the aeroplane in balance, you wouldn't have needed the into-turn aileron.
If, in general, into-turn aileron were required to maintain bank, the spiral dive would not be the killer that it is.
