Its very rare for these RR engines to surge or stall, maybe with a tailwind or not coming out of full reverse before 80 kts.
But reducing the throttle will stop this as 411 stated.
Not as good as a G/E engine but much better than a Pratt.
Lockheed made a good choice for this airplane with the RR engines.
Happy Haj flying for phase II.
Not in it this year but do enjoy the stories.
