John_Mc,
The reply given by
Sciolistes is absolutely correct!
(1) When stalling in a STRAIGHT winged aircraft, actively apply rudder to keep the wings level, avoiding the use of roll control (Ailerons), and
(2) When stalling in a SWEPT winged aircraft, actively apply roll control to keep the wings level, avoiding the use of rudder.
Basically, it's one more opposite between props and jets, both intended to avoid uncontrolled wing drop and possible spin.
NOTE - If practicing "Approach to Stall" (Stick Shaker) in swept wing aircraft, you MAY get away with inadvertant rudder use. In the fully developed stall, such an action is LETHAL.
