Sheppey, you are correct, training aircraft are benign. That’s why people are getting away with using rudder to pick up the wing back to wings level. Do that in some of the high performance experimentals and they will bite and bite hard.
As for how to set up a wing drop stall in something like a Cessna, I find 1500RPM, flaps 20 and a gentle turn to the right. Unless the student is brilliant with the rudder it will inevitably drop the wing to the left. With the right bank that was on initially it gives time to catch it if the student messes up the recovery before the aircraft ends up on its side.
