With today's digital servos trying to maintain near perfect centering, I think it's worth mentioning that if your linkage isn't running free (no detectable drag), or your end points (both of them!) aren't set so there's a little extra room on each end, you're going to smoke servos until you get it right.... makes no difference what you paid for it. From what I see here, as well as some of my own experiences (I smoked 2 servos getting one plane right) there's enough trouble here where extra time spent getting the throttle set up just right pays handsomely!

Point being, I think it's as much or more about setup as it is about having the "right" servo. That's my thought anyway. -Al
