TOTD - yes, but as you know the HC2 flew many thousands of hours in the RAF (and Mk5 in RN) with no major issues. One TR drive failure back in early 90s due to the disconnect coupling coming apart during a simulated ASE emergency but certainly nothing like the MR mast failing.
Plenty of pilots found ingenious ways of breaking them but they were inherently sound.
Spares were the only issue towards the end of its life so I don't know how Fordy.mat has got around that.
