Ptero D. You are dead right about the danger of pulling back a RR Dart engine.
During an instrument take off in an Avro 748 (yes!It was that long ago) I simulated an engine failure by quickly pulling back the throttle on one side. The student under conversion reacted very rapidly to the compass indication of yaw and whacked on full corrective rudder.
As you stated, the prop coarsening caused a momentary indication of yaw in the wrong direction. As this happened a few feet after lift off, we very nearly put a wing into the deck. My idiotic fault for not realising this could happen with a RR Dart. But then, the Avro test pilot at Woodford in Cheshire did not tell warn us about this either.
