You may know it is different, but how can we know?

Please post a link to the datasheet for the servo you are having a problem with.

What's so different about them? They look fairly standard to me in terms of drive requirements, as long as you ensure that your power supply can handle the current, since they're very high-torque.:-

Is there something I'm missing? (You should be able to use the standard "Servo" library.)
