I was teaching slow flight today. trying to do it for a whole hour was going to be too much, so I just introduced the basics of what slow flight looked like, and how to recognize when you shouldn't be doing it. then how to do mit properly when you
should be doing it (low viz etc).
The rest was over to stalling, with slow flight to be revisted over the coming lessons.
with all flight training, practical applications are what we need to emphasize to the student - i.e demonstrate the
situation where you might get into stall/spin (or need a steep turn, or do a forced landing), rather than just showing the exercise by numbers.
There's nothing like
youtube (about 50 sec in) to get a few clips of model aircraft getting into stall/spin crashes
