Un-coordinated flight was taught, is taught, and should be taught. Or did they "cancel" that too?
There is a minimum speed and AoA and total energy that the inside wing has to maintain during a turn, to prevent the wing from stalling. If the outside wing has higher energy than the inside wing, and the inside wing is still flying, then what of it? Only if the inside wing stalls before the outside wing, do you have a partial stall and probably an incipient spin.
OK, so now you have a partial stall... my instructor (and the instructors for many of us here) made me do that a hundred times. It's like skidding a car around a turn. Your groceries may spill out of the bag on the seat next to you.
But if you skid through a turn in such a way that the inboard wing does not get down to the speed/AoA where it lets go, then nobody needs to soil their undergarments.
In a Cessna 150, you may be able to do this skidding turn at 50-60 mph in level flight before the inside wing lets go. In the Storch, you may be able to do it at 30 mph, because that's the kind of aerodynamic performance that makes the Storch worth having.
The only reason for soiling any one's undies is if the person in the Storch was experimenting with that kind of flight for the first time at low altitude, instead of doing it at spin recovery altitude. Or doing it over somebody's house, or the proverbial schoolyard.
