This is something i've not quite understood. I've seen alot of pro pilots say they don't bother with rate even for setting the helicopter up mechanically.

At anyrate, if you are flying in rate mode, some kind of revo mixing is nescesary is it not? The tail won't hold otherwise? Or am I missing something here. They don't tell you to use revo mixing in the manual, even for setting the helicopter up mechanically.
