Unlike an idle stall which gave plenty of warning and no wing drop, at full power this gave no warning, and the aircraft went straight into incipient spin - disconcerting when I found it the first time.
Interesting though your experience is Genghis, we shouldn't lose sight of the original observation at the top of this post.
The aircraft concerned was a Cessna 152. Like the vast majority of aircraft in the GA fleet, the 152 is certificated under FAA Part 23, and most foreign certification (including our own) is substantially on the basis of that testing.
Part 23.201 defines the stall tests which the aircraft must be put through for type approval, and it will be of no surprise that power-on stalls at full power are specified as part of the test program for aircraft such as the 152. A requirement for a satisfactory pass of 23.201 is an early and pronounced stall warning prior to a stall.
There should be no suggestion that a C152 requires the extreme skills of a test pilot in order to perform a power on stall without the risk of a spin. Indeed, tens of thousands of FAA pilots got their wings in 152 and all will have had to demonstrate proficiency at the manoeuvre.
