Servo issue?

[Darren Wales]

I have just purchased a some new electrics for my 2nd car and when i have connected it all up the metal gear servo is making a jerking sound and jerky movements!!
i have also connected it to a new sensored 10.5T combo. The motor seems to be fine.

Any advice fellas?
:confused:

I have tried my old servo with the same set up and thats fine, so this one is going back im afraid. :thumbdown:
