Regarding Gyros ... Yes, this is exactly what a gyro in "rate" mode will do. You (and the heli gang) are correct that it will _not_ hold the correction. It will pulse to stop the yaw, which is exactly what you want. The point is that the gyro acts fast to the engine out. Of course, once the gyro corrects the yaw and releases the rudder, the plane will want to yaw strongly again! And the gyro will correct again. The plan is to keep the plane from entering a spin, not make it fly straight and true. Achieving this will require tuning the gain on the gyro in "rate" mode to get the desired affect. So, when all is said and done, the gyro is buying you time to realize that the engine is out, so the pilot can provide the necessary control inputs for a controlled landing (hopefully on the runway).
