APM 2.5 Jerky/Jittery Servo Movement

Posted by Reid Williams on October 19, 2013 at 9:05pm

Hi, I have APM 2.5 installed in my Skywalker X8. It is powered by the 3dr power module and the servos are powered by a separate BEC. I am getting servo jitters and jerks in all modes for some reason and cannot seem to isolate the problem... I am using Hitec servos along with Frsky Taranis. I connected the servos directly to the receiver and it is buttery smooth but through APM it is crap. With the X8 the jerks are noticeable when flying... Any ideas?

Hi Reid,

Did you solve this issue. I am also facing this problem. I am using PixHawk.

Try power the servo from the input or output rails, this worked for me
