gadgetguru,
you may be intrested to know that Australian Aerody is not the same as the US Army version of events. Having had to study, and qualify, in each "version" of the truth my advice is to forget your search as it will be irrelevant in large sections, and omits important sections of the Australian Syllabus. Ring the Army Aviation Centre in Oakey and try and get a copy of thier latest course documentation. If you do manage to create an "e course" of that sylabus, they would probably be intrested in buying it too!!
Also try Principles of Helicopter Flight by Hank somebody (Wagentock?? sp?). Cant remember his name, but it is a great book.
Cheers
