So far in my experience (still learning to hover/tr) it seems that when using "3d" rates I tend to over-control a lot, even with up to -90% expo. Not overcontrolling to the point of falling out of the hover/tr, but it looks sloppy b/c I have to start correting my corrections. What I found works best is to use a "normal" slightly high rate w/ about -30%-40% expo which lets you stay on top of things without overcontrolling. When you really need a big correction, use full throw with a quick burst of power. I guess I can do it better than I can explain it, but that's what's working for me.

All in all the most important thing seems to be learning what the plane is normally going to do. You learn to recognize and even anticipate things, and eventually you'll be correcting for things before they happen.

And G2 DOES help a lot!
