Robinson has released a bulletin for the fitment of a full throttle caution light that will warn the pilot BEFORE the engine / rotor RPM starts to droop.
I think this is a great idea and should go a long way in preventing oopsies. =D>

I think that it will cause as many 'oopsies' as it saves :) You now rely on some AME to set it up to trigger at the correct moment. What if there is an additional 1/2" manifold pressure available that might just save your butt. Just an unnecessary distraction, in my opinion, but heck, the 2000hr Robbie pilot might benefit 8-[ .

SB89
A main rotor blade modification on (what seems like) the new type of blades.
