I have two new 9252 Digital servos. I am installing them on the Rudder and Elevator of my new Flip 3-D. Once I connected the linkages I noticed the movement of the servos is jerky. When returning to center they oscillate back and forth very rapidly, (just sort of nervous) before finally settling at neutral. If I offer some load to the control surface the motion smooths out and return to neutral is crisp. Is this normal ? Should I be concerned ?
The situation is more pronounced in one than the other, but they both do it.

Xmtr = 8UAPS
Rcvr = R148 DP
Battery = 4.8 volt pack

Thanks, Robert.

Hi Robert,

No, this is not a problem once you have load on the servos or once the voltage drops a little. What you are seeing is the servo seeking center, which is very common on digital servos.

Again, once there is a load on them, or once your voltage drops a little, this should quiet down.

I hope you find this information helpful. Should you have any further questions or concerns, please do not hesitate to contact us at 217-398-8970 for Support, 217-398-0007 for Service or via fax at 217-398-7721 or by email at [email protected].
