Make sure you are using the proper servo save and that your linkage is not too tight.

You can always send the servos in and have us take a look at them. Sometimes a worn or dirty pot can cause this.

The 645 servos are very powerful but due to the 3-pole motor the centering is not as good as that of the coreless motor and or digital servos.

You might try the HS-525MG for touring.

thank you mike
i have both 655 and 645 mg servos
all of them are very new i just can't get them to center to the same place every time
