I have a couple of 9g mini servos attached to my board and I am getting some odd artifact from them. One of them will rotate one direction fine, then as I try to rotate back, about half way through the rotation, it starts to flutter uncontrollably. The second servo opens a gripper but it will not open completely all the time and it never closes completely (always leaves a 1 inch gap). I have tried them both with horizontal and vertical servo controls. I can take some video tonight when I get home and post it.
