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?

there are some RC heli's that have no flybars but you really add to the complexity of the system. To stabalize the rotors you need an additional 2 gyros I believe, which adds alot of weight to these small heli's. Basically the flybar is a mechanical way of keeping the blades where they should be, you can do it other ways, but they add more expense and complexity to the system not to mention weight and cost is a given. Alot of the RC ones are just to mimic the scale flying of real heli's. I have no idea though by real heli's do not use a flybar system very often. I guess that's what your realy q is?
