Y'know, those training hacks are bl@@dy hard to viciously stall. With power off they take forever to reach stall buffet and by then the horn has been blaring a while and the stick is right under your chin. With power fully on the wing drops are slightly more interesting but even with the horn blaring the b@stard thing still manages a positive climb rate.
Go out there fly a certified aerobatic aircraft ( For your safety) with a competent instructor, try different scenarios, incipient stall, aggravated stall (Falling leaf) fully developped spin and recoveries, takes 1 flight to demonstrate, many more to master, but worth a 1.000.000.000 words.
Fully agree, it should be part of the training syllabus. Exploring the stall in a more slippery certified craft does wonders to one's overall handling skills in this area, to the point that it becomes a non-issue.
