Hi cl12pv2s,
The Robinson doesn't have a lower coupling shaft like the Schweizer - the lower pully is bolted directly to the engine. However, a damaging engine overspeed is much more likely in a no-load situation, as there is little inertia to prevent mega-RPM transients.
I too am curious about the reason for the governor on change. I was trained to switch the governor on prior to rolling the throttle up past 80% during final run-up. The governor then takes the RPM to 104% Oh well, I'll be psyched to hear a solid explanation from a RHC factory guru!
Keep the big fan spinning, gang.
