Servo Replacement. I know this has been covered, but figured I would share my experience... This is a bulletproof glider servo setup without having to reverse polarity or request counter-clockwise setup from limited vendors (you can substitute the servo for the cheaper ones if desired)… VERY IMPORTANT, there is in-fact a hard stop on the glider and you absolutely have to set the center correctly (probably not default 188 setting) so that far left and far right DO NOT hit that stop. You will notice that the parameters actually change during test if you go from x to y quickly back and forth, so make sure you really let it have it. Mine hit going left at stock when going from L to far L very quickly and repeatedly, and the servo would just continue to whine trying to break past the barrier to the set point. Your servo SHOULD NOT continue to make any noise after it hits max left or right position and the black stop under glider should never actually touch the outside edges. You want the software to limit, not the physical points, that will break your servo.
