Well all the advice given to this post sounds good on paper ,However in the three years needed to prefect the hovering gig I've found that only the V E R Y overpowered planes Such as the profiles with 91 Satio or to that efect will be a problem. The continuios throttle transition will cause the airplane to torque over to the left. When you get more experence it's a great lesson to remove all the thrust and even set the airplane up a little nose heavy. In other words (remove the tranning wheels). Hope this helps... DAVE
