how come real heli's no have flybars?

could it be the size and weight of the rotor blades on a real heli makes them not needed?

what if we weighted our blades with the flybar weights (to mimic the full-scale), would it work without the flybar (and reduce the weight by removing the flybar and mounting stuff for it)

feeling very pensive today i guess - these questions keep going through my head like rotor noise in the far off distance

if, in a single-rotor heli, rotor noise is caused by the forward moving blades going supersonic (or 'slapping the air'), producing the 'thump thump thump thump thump' waves, would a large coaxial sound like a fart?

thump thump thump thump thump thump thump thump thump thump thump thump
