When I experienced the T/R failure at the 1999 Biggin Hill Air Fair display, I was flying the FX version. I had the devil's own job putting the heli down safely mainly due to wrestling with the throttle the co-relation.
Denissimo! This is doubtless testament to your super-normal
aviatorial skills and of which we are all so proud!
Speaking of FX's and tail-rotor 'issues' .. you must of course have seen this clip of an FX (Stateside) which encountered a 'stuck pedal' scenario:

From what I have been able to glean on this craft, Denissimo displayed her at the 1976 Farnborough Airshow and also entered her as a contestant for the British Helicopter Championships .. and doubtless many other occasions too!
