I meant to comment on this earlier but forgot.  How did he do that?
Everything I've ever heard said the rotary runs rough as a cob on one
rotor.

I was thinking about that myself. Perhaps all the experience we have
had on this is only with Tracy's PSRU and a prop load.

Perhaps what causes the roughness is the one torque
pulse per rev rather than two and the gear box rattles due
to prop inertia load and resonant problems. It might run
smooth with no prop.
