If I have been following correctly and you said
"The aircraft was within w&b for normal category flights, in my opinion it should have been in utility category for a full power departure stall."
May I just add in my humble opinion, that for ANY stalling excercise, in any config, the aircraft should be in the utility catergory, at least for the Piper singles I have flown, 140, 161, 180 and 210R.
