Ah, I get it. So the problem is with harrier wing rock which is messing with your transition to hover. I would check your lateral balance and make sure its on. Then make sure all your surfaces are even. Bottom line, though, wing rock in harrier can be controlled. You just have to really stay ahead of it, correcting with the ailerons this instant the wings start to roll. The quick, little correctings required soon become second nature, and so fast nobody really sees you correct or the wings rock. learned to do it in G2, which I was told was a great way to learn because if you could harrier in that program, a real model would be a piece of cake. Anyway, its something to practice. Try just getting into your harrier with the plan of making one or two corrections and then flying out. Do stay in it until it becomes a mess. You'll master this quickly and then begin to lengthen the time you can stay in harrier. In time, you'll develop a feel for it in straight lines and turns.

best of luck,
