Buzz Dave nailed it. People who think they are ready for this type of plane can now afford it, but they are not really ready. All 3D planes really should be set up with dual rates, for the two types of flying they will do, flying on the wing and flying on the prop. There is a big grey area between these two areas of the flight envelope, and some planes are snappier than others in that area, some allows you to mush the plane in that area. There are exceptions where high rates can be used at speed, like the Wall, Blenders and perhabs other maneuvers, but if the pilot is inexperienced, you will hear stories about the plane snapping with too much elevator, dooooooooooo, all planes snap or stall with to much elevator when flying on the wing, or the elevator stalls.
