The foam blades are just fine for learning to hover but do not arrempt even a hovering auto with them. Your pitch range sounds ok for learner set up but once you get into forword flight I would recomment a little more neg at bottom stick. I order to shoot autos you are going to have to some deacent glass blades that are heavy but I can't really tell from your post where you are in the learning curve, good luck and pratice, pratice.
