Heading Hold Gyro as a Sensor?

Hi,
I wondered if anyone had every tried using a heading-hold gyro from an r/c helicopter to assist with navigation? I.e., point it in a direction and as the platform heading changes monitor the output it sends to a (non-existent) servo as it tries to make a correction; an input to the servo could be used to change the reference heading. A lot of them have responses that are re-programmable.
It is not going to be able to point in a direction in absolute terms but for those "left a bit" / "right a bit" situations it could be useful - or would it? E.g, I have a GPS that outputs current heading and the heading that is required in order to get back onto the planned route: "left a bit", "left a lot", could be useful.
Getting a relatively cheap, off-the-shelf and small solution performing all of the difficult calculations seams a good idea - could it be too good to be true?
