Step whilst I am pleased that you are considering to learn something new, may I suggest that it would have been more prudent to ask for the assistance you now seek a lot sooner rather than later on subjects that you are unfamiliar with.
Unfortunately, I do not have the links to hand but I am sure someone will be along and post them for you.
Do I think it's wrong to promote instruction for skill ? Of course I don't! However, our 'experts' here took spinning out of the PPL syllabus. Why? Because too many of those 'expert' instructors were allegedly killing students demonstrating spinning characteristics.
Where has that put us? The low time ppl's that may spin in and have no practical idea of how to recover. Progress eh.
