have not read the full thread, but I have to say this.
power on stalls are very useful if you get the chance to experience them, often with surprising results that most of us would not realise happened until we performed them.
I did power on stalls in my PPL, and I now know why they are taught.
you **will** find them useful .........honest, especially if you do aeros, and what the hell, it does give you a better feel for the aircraft.
