Had experience with both @ Ft Eustis VA Aviation Applied Technology Director it in. The mid 1980s Most Professionals There Considered The YUH61 The Better and Safer Aircraft!

Except that the Sikorsky prototype cold lift 2000 lbs more into a hover than the Boeing.

Possibly a better aircraft than the 60 but lost out because Boeing could not figure out how to get rid of the vibration caused by the main rotor passing over the tail boom. The mast was limited in height so as to fit in the required AF transports by simply folding the blades. Sikorsky solved the problem with a taller, retractable mast (greater clearance over the tail boom), and they allowed the gear to kneel.

Better thought out than the Sikorsky model in every way!
