Upgrading Base Rotate for robotic arms

Hi,
I built a AL5D robotic arm and am looking to upgrade the base rotate so that it spins more than 180 degrees. Would this be possible with a continuous rotation servo? or would I need to do something else?
Thanks so much,
Chris

At this time we do not have any specific options to have the base rotate over 180 degrees while being able to control its position. The Hitec 1425CR can be used, except you only have control over the direction of rotation and speed, not the position it moves to. We apologize for any inconvenience.
