    No where it's explained as good as it has been explained here. I ve been trying to understand the functioning of the stabilizing bar from so many places. This one just nailed it.

      Now think of the genius idea of model RC helicopter manufacturers who implemented both the Bell stabilizer bar AND the Hiller-type paddles whose functions are mechanically mixed via a "Bell-Hiller" mixing arm into one integrated device, called "flybar" in RC helicopter parlance. This is of course mostly outdated in modern RC helis, as most of them nowadays use computerized "flybarless" stability and control systems. I still fly old-school, mechanically stabilized RC helis, a Min Air Spectra and an Align Trex 450 V2SE, both some 20 years old and going strong.

      @@dchuru24 From what I understood, the dampers add a degree of "fixing" the stabilizer bar's orientation to the mast, reducing its tendency to remain in a fixed plane in space, thus limiting its stabilizing action.

    I love these old explanation videos, they're so good at being clear.

      That is the difference between trying to educate the masses and trying to educate a few, while protecting intellectual property to retain future profitability.

    Not 90 deg with the rotor blades, 90 deg with the mast.

    Instead of chopping off the end, he should have attenuated the lengthy, motion picture, musical intro.

    I often see that Bell helicopters with two blades always use bar stabilizer. But helicopter with another brand does not use. Ect Robinson helicopter. Am I right?

    • @antigrav1302

      True. On the Bell 47, there is an FAA approved Supplemental Type Certificate set up that allows the removal of the stabilizer bar, called the Texas No Bar Kit. The 47 is still flyable without the bar, just a pain in the butt, I never cared for the way it handled without the bar. Removal reduces weight and decreases cyclic control response time for AG spraying operations. Bell removed the stabilizer bar design from later production helicopters, ie Jet Ranger, blades have more inertia which made it a little easier to control, but still more sensitive than the stabilizer bar design. Hueys retained the stabilizer bar back in the Vietnam war to make it easier for low time teenager warrent officers to handle.
