Causes of abnormal servo jitter:

Reasons for abnormal servo jitter:

If it is not connected through welding, there are two possibilities:

1. Cheap servos have the problem of gear error, which is easy to cause backlash, so the servo is constantly corrected

2. Possibly poor resistance

If it is connected through welding, there are several possibilities:

1. The resistance may be aging and worn

2. The servo speed is too fast, causing excessive repeated corrections

3. It is connected by steel wire, which is too elastic

4. The extension cord is connected too long, causing interference

5. Broken

Servo is used in the RC aircraft model jitter in the following situations:

1. Jitter when flying at high speed -1. Please check whether the servo rod is not tightened. -2. Please check whether the servo rocker arm's rod is too large and there is a gap.

2. Do not use Y connection cable if using digital servo.

3.Whether the voltage is insufficient.

4.Whether the servo is broken.

5. There is a problem with Rx or Tx signal transmission. [The antenna of the transmitter is not pulled out or the antenna of the receiver is broken.]
