January 28, 2014Application(s): kinematics control
Comments: Few weeks ago i bought 3 of these, for some reason one has a range of 180deg and the other two only 170deg. I suspect they are not all assembled with the same accuracy.
For my purpose these servos where ok (cheap and good usable)
Though next time I'll try the metal version.
The good servo sounds smoother then the other two.
