You got the point. If they did what you want, the elevator will mix with rudder to compensate the shift of piro. But Walkera only give us a very simple type of gyro that only stable the direction of yaw axis when piro. The tilt plane of hover will make the shift in piro. If you like, turn the plane to exact horizontal (of cousre it will drift a little whenever one do this) and start full speed piro, the bird will keep in place for two or three turns.
