Got mine out for the first time this morning and noticed the same thing. I attributed most of it to crappy servos. Never, EVER, buy any Blue Bird 621MGs. Hitec HS55s have more holding torque than these things. From 0-20 degrees, I'll bet it doesn't have 15oz/in or torque. Plus, the last 5 degrees of throw take over a second to get to the commanded position. The worst part is, it only does that in one direction, so if you have them on elevators and the servos move in opposite directions, you get some really bad symmetry. I couldn't get over 1/2 throttle without the elevators blowing back. As soon as some more money is available, I'm loading up on some Hitec 5645s.
