I said it was a problem with my Lightspeed but they basically seem to feel that since nobody has died yet from not hearing the low RPM horn they don't need to address it (and of course if there is a fatal you probably won't know that the pilot couldn't hear the horn, just that for some reason he never lowered the collective).
Well, Robinson is offering it now. On all new machines give low RRPM warning through headset only. No more buzzer. Working headset is now a pre-start checklist item.
