Congratulations on the successful recovery of a bad situation! So glad it was you....and not me. Have you tried to replicate the pedal settings, airspeed and power setting....and played about a bit to see how slow you could get before it all goes blurred?
The question I have....and the answer would be most educational...how was it you arrived at the decision to take the course of action you did? Sounds like it was a pretty exciting time for a while and thus you had to make some pretty darned serious decisions quickly.....an account of what the thought process was would make for interesting reading.
I know from experience when you have caste iron failures in these things....there is not a lot of time to go read a manual. Tail rotor failures are one of those things we spend not enough time talking about or practicing....and those failures require some pretty sharp thinking to get the aircraft down in a re-usable condition.
Well done!
