gadgetguru,
Brilliant idea. I always really struggled with concepts like flapping to equality; the only way I could understand it was to visualise it, and I'm a very poor visualiser. As to what's needed...everything, from the basics onwards. If I think of anything more specific, I'll certainly let you know. Would help me a lot now I'm supposed to be able to instruct on this stuff too.
Just had a thought - what happens to different parts of the rotor blades during autorotation would be a good one...always found that hard to understand - and learning by rote is not the same thing as understanding.
