Have you flicked the switch to rate mode to see if it centres then?

Neither of my helis, one with a 401 and one with a GP750 return to centre when in heading hold, unless driven back that way by movement of the tail.

I would reset the gyro configuration and re-test it for both rate and AVCS modes.

The manual is available here

yes it stays in the same position until you centre it then all seems ok until you move the stick and you get no movement until you sentr again
