There used to be Origami pages in the old "Rupert" annuals and one of them had the best design I ever came across for a paper plane. You could easily alter the elevon angles to perform different acrobtics.

The trouble is that it was so complicated that I could never remember how to fold it without the instructions and the book has long ago disappeared:(

I can remember how to make one that was about 75% as good ( and about 50% as complicated).
