Disabling RigidbodyFirstPersonController

Quick question,
im trying to disable the RigidbodyFirstPersonController script from the new standard assets.
However whenever I try this

gameObject.GetComponent<RigidbodyFirstPersonController>().enabled = false;

I get the error, The type or namespace name `RigidbodyFirstPersonController’ could not be found. Are you missing a using directive or an assembly reference?

Im guessing its because RigidbodyFirstPersonController is in a different namespace?

Thank you

You are correct, just include:

using UnityStandardAssets.Characters.FirstPerson;
