Power Cleans Technique

I’m having a bit of a problem getting the proper elbow whip(power cleans from floor). I have no problem with weights just 5 lb under my max but anything heavier I can’t seem to rack.

As I am just learning to do full cleans they are serving as a warm up to my power cleans from the floor.
And by doing it this way my first set or two of power cleans seem to fly up.

I just have to figure out that elbow whip.any suggestions
