David Scott, does a very nice job in his series of spiral bound manuals teaching everything from beginning to advanced in an excellent format. He's the owner of the "First RC Flight School" I think and has been doing this for quite a while. I used these to demonstrate advanced procedures to my kids. Other than those there are a few others out there that are not as complete. I also subscribe to every RC magazine there is and the aerobatics forums as well. I'm sure others will have good recommendations that would yield a complete reference.
