Whilst my page is not specifically aimed at instructors there are a couple here available for download.
NOT JAA Syllabus but 2 relevant to helicopter instructors. The ones I refer to are the transport canada ones.
There is also a set of commercially produced helicopter notes if I can find the link when I get home tonight I'll post that aswell.
