August 31, 2020Application(s): Robot
Comments: They do the job poorly. Lot of jitter and noise without even a high load.

September 30, 2014Application(s): 3dhs 41"edge ailerons
Comments: Both servos seamed to be functioning fine however when I measured the throws 1 was 20% less then the other. I tried them on a wye to see if it was radio or receiver related (same outcome)I went back to seperate channels and mixed out 20% from the one and still had my full 1.5 inches of travel (problem solved) however this should not have been necessary and must indicate 2 different pot readings from what I see the pot quality control must be poor.

September 26, 2014Application(s): Tail servo on 2m TD glider
Comments: Got the jitters with less than 10 hours of use, clearly a potentiometer problem. Servo was not stressed at all during use :_(

May 16, 2012Application(s): EPP foamie
Comments: The potentiometers failed on all 3 of mine, starting with ailerons on around the 40th flight. I rotated the servo horns one notch and used sub-trim so that neutral would be in a different spot on the POT, but the new spot is already starting to get jittery.

January 13, 2012Application(s): Small to medium gliders and power planes where thin servos are necessary
Comments: These are quite good. They are thin. But the torque is not high. They are fairly resistant to stripping, but they will strip. They are noisy. Overall, quite good for applications where a thin, light servo is required, but not amazing or anything.
