It's not really rock. It's just that with a full 88 degrees of elevator movement harrier can be a little tricky. With that much throw it is easy to rotate the plane so hard that you dump whatever partial lift you are getting off the airframe. In harrier you are right on the ragged edge of a complete stall, and having the elevator authority to rotate past the critical angle of attack can put you over the edge.
Once I figured this out I started concentrating on using less elevator in harrier and that helped. We have never had this kind of elevator movement to play with before, so it's a bit of a learning process.
Lately I've been setting my low rate for 100% rudder and ailerons, and dropping the elevator to 50 degrees. Basically, all I have is a high/low for the elevator only. Low is my harrier and general flying around rate, and I use the high rate for tumbles, walls, parachites, etc. This works well, but I'de rather fly on just one rate, so I have just learned to fly the plane on high rate and work on getting my harrier better.
