Yep, I forgot the flap, they drop the left wing under power so I used to demo from a right turn. Of course the last of my 1000hrs+ instructing in two seat Cessnas was 25 years ago - I presume they still fly like that!
"flow strips" on Traumahawks killed it's spinning as well! They were scary though when you turned around and looked at the tail!
Just look at the Beech 1900 to see a poorly designed airframe.
