Ryan has got it on the nose. You have to apply elevator faster not so fast the plane gains in altitude but fast enough so that you can get the nose up high like high alpha flight. Then when the plane stalls the nose comes down and you initiate the autorotation. Do not wait to long to start pulling. if you wait to long the nose will not come up. This takes alot of practice because every plane is different and you must know your plane and be able to judge its speed well.
Good luck
