Joe,
If you think that going digital on the elevators was a big improvement just wait till you see how the UCD will wag it's tail with one on the rudder! I know a lot of people don't think they need them(I was one of them) but there simply is NO comparison. This is especially evident when in a hover and the plane starts to fall out, with the standards I couldn't hold it and had to fly out, with digi's it's no problem, I can simply SHOVE the plane back into the vertical.
