If you can access the archives @ Ft. Rucker, AL, USA, I'm sure you'll find an amazing video of a flight of 3 Hawks . Number 2 (stag.rt) T/R is completely stopped and continues flight for quite some time. The crew were oblivious to the malfunction. When we went through the AQC this film was part of the Malfunction Analysis course . Also, in the flight sim, it's possible to keep continued flight up, but it's directly dependent on the G/W and of course the pilots abilities. The chord on the fin is pretty powerful, just the way Igor wanted it to be. Sikorsky had so much faith in it's ability to help you out in case of a T/R problem, they even describe the airspeeds and techniques in the Emergency procedures. The Mixing Unit has a certain part to play, but then that is related to the overall G/W.
Did I mention the T/R produces 2.5% of the overall lift. Would this have an effect too???
