Tim, I think the real reason for expo is for newbies who over-control. And bless the technology for giving us expos. Even us old timers could use some once in a while. I find, for example, that -40 expo on the Futaba 7CAP, allows me to hit full throttle or all the way down without messing up the line of flight by a slight left or right of the stick, inputting rudder. The 7CAP, new to me, is better than the 6EXA in that regard because the sticks' tension is adjustable, hence you feel the center more, and when off center, better.

With the 6EXA the rudder has no expo because it has no high/low rates or expo at all. The 7CAP fixes that.

Waldo will tell you you simply need to educate your thumbs: don't over-control. The real problem is not the plane, the set-up, or the radio. The real problem is staring back at ya from the mirror. That's the hardest lesson I had to learn, but once DownTrodden taught me that, I began to learn to fly.

Expos makes the transition easier, I'll give you that. But the goal is 100% throws and no expo. Yet, a pro told me that when competing, you can set up your radio to give THREE adjustments for throws and expos for given maneuvers. I ain't there yet, but I understand.
