This discussion has been had before....probably a couple of times.
Refresh my fading memory as to why just making stronger PCL's and marginally stronger hydraulic jacks would prevent the problem although allowing honest to goodness RBS?
I recall one wonderful old Sikorsky and a venerable Bell product that with youthful indiscretion could both demonstrate RGS for the young and dumb. (Hand raised!).
In those aircraft with correctly turning rotor heads, the nose would pitch up and roll left....and the airspeed would bleed off till the RBS abated or ceased....and assuming one was wise enough to reduce Collective to a reasonable cruise setting....normal flight returned.
Surely some Whirlwind experienced Pilots had some exposure to that.
In the early CH-47....A Models being grossly over weight could provide occurrences of reactions very similar to RBS but in both heads....and with contra rotating rotors....;think about how those symptoms were manifested!
