C150 will drop a wing if you look at it. C172 less so.
The Cessnas will only encounter a wing drop *after* a
power on, full flap stall. I have never encountered any wing drop on either c152 or c172 with zero flap & power off.
The only other aircraft I ever flew that had a nasty wingdrop in a clean configuration was a piper traumahawk .. guaranteed they dropped a wing every single time clean
