As for what could the pilot do to promptly increase the rudder (and elevator)effectiveness... a little burst of power would help a lot, though it takes a bit of practice to know how much and when. Since this was a rotary... it may even be easier due to the blip switch and the need to keep that engine turning through the roll out.

Bald Eagle, what do you think?
Rob,
You were the first to answer the second question I asked at the beginning of the directional control discussion. For that you get a big attaboy.
It is such a simple thing, but a burst of power when you are having control problems can often quickly stabilize the situation and save the day. A good thing to have in your bag of tricks.
The following tale involves a more modern aircraft and a different axis but should be illustrative:
I was a newly minted pilot and I had checked out the club Cessna 150 from the FBO where it had just undergone maintenance involving tail removal and re-installation. I checked out that the control motions were in the proper direction prior to flying and launched. On my first landing approach with full flaps, I was flaring the aircraft above the runway, still nose low, when the elevator hit the stops! I reflexively gave the aircraft a burst of power and got the nose up enough to land it. I checked the elevator and found that the elevator bellcrank had been mounted upside down. I had lots of down elevator and very little up elevator.
I don't know if a burst of power would have lessened the swerve in the Dr.I that we saw in the video, but that was about the only option left at that point.
