"He who plays with rudder at the stall invites a spin"
I did my basic flying training on RAF Chipmunks, back in the sixties. We were specifically taught to pick up a wing drop in the stall with rudder. It was emphasised that the application of aileron to an already stalled wing could invite a spin.
Some ten years later, I did a PPL refresher course on C150s(ish). My civilian instuctor used aileron to correct a wing drop in the stall.
I was intrigued, but just did as I was taught for each aircraft at the time.
